Scopes, Scopes, Scopes.
Firstly let me say that there is nothing new or groundbreaking to be revealed here, this is merely a one stop shop for my scope research carried out over the last year, whilst some of the information here I truly found for myself I do not claim to be the originating source for any of it in the broader context and indeed most of it is based on the work others have done; someone else has always been here first (with the exception of the Webley 4x20, I've never known thast referenced before). This post represents a considerable amount of research and re research. I have tried to make it as straightforward to follow as possible. I have written it this way to place all the information in one place at one time. The original post has been edited and re edited many, many times as new info or better pictures came to light. It's a long post in order to place all the available research in one place.
My original Frankenscope thread to be found here: http://www.thedentedhelmet.com/f20/e...c-heavy-45034/
These vintage scopes were made in the Japan. The models of interest to us all feature the strange infinity type symbol. This symbol is very important: some of the brands referred to make 4x20 scopes that feature different symbols and they are inaccurate (take note if hunting for the ASI - see below).
The infinity symbol
The scope is a 4x20 specification. 4 is the number of times the image is magnified and 20 is the diameter in millimetres of the objective lens. The size of the objective lens effectively controls the amount of light that enters the scope and controls the quality of the image and the conditions the scope may be used in. The bigger the objective lens, the more light and better quality image and so forth. A 4x20 is an entry level scope and whilst the Japanese built optics are of reasonable quality they are by no means exceptional. This is the case for modern 4x20 as well; there is apparently not much point in making 4x20 of exceptional quality due to the limitations of dimensions. Most serious shooters seem to have at least a 4x32. A 4x20 would generally be attached to a 'plinker', a low powered air rifle for use in back gardens to be used shooting at tin cans, just for fun.
In these next two pictures see a period ASI 4x32 Deluxe (that features the same infinity symbol) both in close up and next to both ASI and Hunter Brand scopes with their original mounts. There is no doubt that the 4x32 is a thing of quality and the 4x20s are not!

4x32 and 4x20 comparison
A vintage EE3 4x20 Scope.
The retaining ring in the objective bell loosened:
From left the right the parts are:
The eyepiece, which contains the ocular lens.
The locking ring to lock the eyepiece in place, if looking at a scope has a variable zoom (which this isn't) then a ring in this position may sometimes be called the power ring and is used to adjust the magnification of the image. As a sidenote: The greater the magnification the greater the vibration i.e. if you magnify the image by a factor of 10 then you magnify any movement by the same factor. Essentially this means that the greater the magnification the more important it is that the scope is held steady. Minor vibrations caused by human movement can greatly affect the steadiness of the image when it has been magnified many times (such as breathing or even pulse/heartbeat).
The tube. This isn’t just a tube, inside there are various lenses and apertures to turn the image back up the right way and display the reticule.
The windage and elevation screws. The screws assist in fine tuning the scope to compensate for wind and elevation i.e. left to right/up and down. Sometimes these are referred to as ‘turrets’. The block on which they sit is sometimes called ‘The saddle’. The screw on caps are merely to protect the screws from dirt and grime. The fit of the caps should be true and they should screw on and off with ease. If they seem exceptionally tight or loose then they are most likely not the correct caps for the scope or they have been mistreated and are threaded.
The Objective bell, which contains the objective lens. There should be an additional (retention) ring that screws in the end of the objective bell that locks the objective lens into place and prevents movement or damage.
The Types of Scope:
There are four (and a half) scope types that are suitable for use. For ease they are referred to as types 1, 2, 2.5, 3 and 4. Remember that any scope by type is identical in the characteristics and only the brand markings differ. In this section I have deliberately taken the pictures in such a way that the brand markings cannot be seen in order to labour the point somewhat. A Type 1 scope is a type 1 scope, a type 2 is a type 2 and so on.
Type 1 Features (from left to right).
The eyepiece is metal and I have frequently found in type 1’s that the ring that holds in the ocular lens sits slightly proud of the eyepiece, types 2 & 3 feature this ring but it tends to sit flush and not proud. This may be due to difference of material used and the fact that metal expands or contracts dependent on temperature. I use the word frequently as I have found type 1’s where this ring does not sit proud. The tube is metal. The windage and elevation screws sit in a plastic saddle. The dust caps are plastic and have a conical roof. The Phillips head screws that mount the unit in place have high domed rounded heads. The objective bell is metal and it can be unscrewed from the tube. It has a small has a small lip where it meets the tube so the taper does not run direct to the tube. When the scope rings are attached and in position it is almost impossible to see this lip. The end of the bell has a holding ring that screws into the end. Based on my findings it would appear that type 1 is most likely the earliest of these made and that production ceased no later than 1978. Type 1 scopes are by far the most common that I have found and outstrip the other models by at least five or six to one.
A Type 1 Scope:
Type 2 Features (from left to right).
With the exception of the eyepiece the scope is identical to the type 1. The difference in the eyepiece is that it is plastic. The eyepiece is slightly wider or fatter overall and is approximately 2mm wider where the eyepiece meets the eye. The angles and tapers of the eyepiece are sharper and better defined on the type 2 over the type 1. The plastic has a more reflective finish than the metal and so the definition and taper are easy to detect so long as a strong light source is present but not a camera flash, that tends to obliterate the difference and I have used a flash in the close ups in order to demonstrate this. In soft light or dim light the sheen tends not to betray these differences and so making it very difficult to distinguish type 2 from type 1. The comparison of three types is daylight only and thus the difference is easy to detect. It becomes easier to tell a type 2 eyepiece from a type 1 eyepiece if one touches them as the metal of the type 1 usually betrays itself by being colder to the touch. Type 2 would appear to have been produced later than type 1 as it uses cheaper materials and probably were in production up to 1980. I believe that the Type 2 is used on the ESB hero prop. The link to the gallery picture below demonstrates this very well (as do many others in the gallery). The definition of the angles on the branded eyepice of a type 1 scope simply do not ever look this sharp. I have spent hours poring over the gallery pictures of the ROTJ hero weapon as well trying to recreate the angles of many of the shots using both type 1 and type 2 scopes and having given lots of consideration and taking Lonepigeon's opinion into account (see later posts) I believe that they ROTJ Hero prop has a type 2. I can also add that I am of the opinion that the scope on the hero prop is a real scope, this is because where the paint 'weathering' has chipped and flaked away the black underneath is exactly consistent with the appearance of a real scope. The main body of the hero weapon is be a cast but not the scope. The ROTJ stunt scope and rings apparently are all casts based on my observations of other gallery pictures. Type 2 scopes are far rarer than type 1s.
See comparison section for 'Type 2.5'.
The scope in this picture is definitely a Type 2. No question.

A Type 2 Scope:
Eyepiece Comparison between type 1 & 2. Note the ring on the ocular lens doesn't sit flush on the type 1 (left).
Type 3 Features (from left to right).
Features largely as per type 1 except that the eyepiece is plastic as per type 2. The locking ring is slightly different to types 1 and 2 in that the grooved section is longer and the grooves themselves are both broader and deeper. The tube and screws are the same. The bell is dimensionally different. There is a lip where the bell meets the tube but it is less pronounced than types 1 and 2 but when the scope rings are attached in the correct position it is next to impossible to identify this. The tapered section of the bell is longer than the types 1 and 2. The diameter of the bell at the end is the same for the type 3 as the 1 and 2 and again the end of the bell has a holding ring that screws into the end of the objective assembly. The objective bell cannot be unscrewed. The desirability of the Type 3 scope for accuracy is still pretty good, the locking ring is easily swapped out for an accurate one (can be found on many different scopes but most 4x15 of this period have suitable rings) and whilst the objective bell is off it will be it will be almost almost impossible to spot on the assembled prop with the rings in place. It is my belief that this type of scope was produced no later than 1981 or 1982.
A Type 3 Scope:
Type 4 Features (from left to right)
I did not discover this until long after the original post and I believe type 4 will have come after type 2 but before type 3 in terms of production dates so in reality this should probably be the type 3 and the type 3 the type 4 however I didn't discover this variant until long after type 3 so I'd have to do a lot of editing as well as trying to change peoples usage of now generally accepted terms and create unnecessary confusion. Late 70/very early 80s I'd say. Anyway, the eyepiece is plastic as per types 2 and 3 but has an additional ring added to the utmost end that adds an extra 2 millimetres or so. Apart from this extra length the shape, angles and taper of the eyepiece are otherwise unchanged from the type 2 and 3 plastic eyepieces. The locking ring is the same as the type 3 with the longer and deeper grooves. The rest of the scope (tube, saddle, windage and elevation screws and objective bell) is the same as one would find on the type 1 and 2 scopes.
A Type 4 Scope:
In this section I'll introduce the 'Type 2.5', a relatively late discovery and so called as it sits pretty firmly betwixt the type 2 and the type 3. I have not troubled to show a full length shot but in this section shall attempt to demonstrate the subtle differences in the following few shots. The parts from left to right are: A plastic eyepiece as per type 2 and type 3, the thicker locking ring on types 3 and 4 and an objective bell that sits slightly in the middle of the types 1 (2 & 4) and type 3 in terms of shape. The objective bell of the type 2.5 DOES unscrew.
A comparison of the difference in the locking ring of the type 1 & 2 and the type 2.5, 3 (&4). Type 2.5 / 3 and 4 are on the right. It would easy to swap this out for a locking ring from any one of a number of other (accurate) scopes to bring it in line with the others if it really bothered you that much. Pretty much every 4x15 from this period has the correct locking ring and the 4x15s are generally pretty cheap. Sorry - old photo:
Objective Bell comparison. Types 1, 2 (&4) on left, type 2.5 in the middle and type 3 on right.
On the left is type 1, middle is 2.5 and right is 3. The type 1 scope the taper runs straight to the extra lip or stage that meets the tube. The 2.5 bows out slightly on the taper before the lip is reached and this is bowing is more exagerated on the 3. In the following shot I have added some lines to try to demonstrate. The bowing on the ype 2.5 is very subtle; you wouldn't notice it unless you were looking or if the different locking ring didn't show it to be something slightly different in the first place.
Another shot from a different angle to use the reflected light in order to show where the subtle bowing occurs. On the two circled scopes it is possible to see the extra distortion due to the shape differences.
A few of comparison shots of the differences in the eyepieces to demonstrate the extra ring and length of the type 4.
I really can't stress enough just how similar all four (and a half) models/variants are. Even though I have been looking at these in some depth for some time if I spread a variety of these scopes before me on a table with the branding obscured then I need some moments at close proximity to tell them apart. Once weathered and mounted to your prop replica with the receiver rings in place so that they obscure the slight tell tale sign that allows one to differentiate the type 3, due to the smaller lip, it really is going to take an extremely close examination to tell them apart by someone who really understands each one well. Any of these model variations is an excellent choice for your prop and I wouldn't recommend pay £100 for a type 2 instead of £30 for a type 1 or 3 etc.
Types 1, 2, 3 and 4compared:
Laid out ESB styley. 1 top, then 2 etc.
Scope rings and mounts.
Type A – The hero rings.
These are the receiver rings as used on the hero props for both ESB and ROTJ. As we all know the key issue here is the size of the tabs that are attached to the rings. These are generally referred to as the ‘Tall feet’. The general perception is that these are hard to find and I must resolutely disagree. They are not hard to find and they need not be expensive either (see below).
Type B – Hero rings with short feet.
These are the same receiver rings as the hero rings but the tabs that affix to the rings are shorter. These are commonly referred to as the ‘Short feet’. The perception is that these are far more common than the tall feet variety. My experience is contrary to this but if these are all you can find then they are an extremely good alternative. I suppose it’s possible that I didn’t find so many of these as they weren’t what I was looking for.
Types A & B Compared. There isn't a great deal of difference making type B quite suitable:
Type C – ROTJ Stunt rings.
This comes as a single piece mount that needs to be cut into two and a long section removed from the middle in order to be properly made into the stunt rings. I think that these are a great idea for the ROTJ guys who can’t find the Hero rings; you can use these rings and still have an accurate representation of a screen used piece. To remove the middle section I used a vice and a hacksaw.
A modified type C:
Type D – No use to anyone!
Only referenced and shown as relevant to a certain model, the ASI.
Lastly a couple of comparison shots of mounted ring types a, b and c. All have been mounted on type 1 scopes:
There are several brands suitable, all here have been referred to before but here is some info on availability of variations. It would seem that most of these brands were widely available in the UK in the 70's and 80's, which is why it will undoubtedly be easier for those based in the UK to acquire these items. Brands listed alphabetically.
I have used the best quality images I have available but as you will see some are not great. If you have a better quality picture where I have used a poor one then I'd be grateful if you could supply one and I will update accordingly. Images of boxes have been added where possible in order to assist eBay buyers where scopes are often poorly described and photographed but boxes are often easier to identify. I have only pictured confirmed and original boxes and any cases where I have not been able to verify a box I have not pictured it.
ASI 4x20 Scope.
The ASI is the most popular choice for most people and is the widely accepted benchmark. This is, by a country mile, the most common scope I encountered and I found them in both type 1 & 2. ASI in it's original form only comes with type D mount. The ASI was also (generally) the most expensive option, the problem being that it is so widely known and not just in Star Wars circles. Having frequented many a shooting board and forum it is clear that it is widely known outside Star Wars Circles. Basically everyone knows about it and everybody is looking for one so the price is pushed up. It's likely you’ll need to acquire your own hero rings and tall feet. This scope has been definitively identified on the ‘Nostromo Blaster’ from ‘Alien’ and pictures of that original prop can be seen below posted by Lonepigeon. Interesting to note that the Alien prop features scope mount type D. . The prop company that made that prop also made the ESB EE3 weapon so this gives it provenance but there is no concrete evidence that the ASI is correct scope but merely the first brand identified that was a match. With that in mind there is no reason you should pay more for an ASI than any other brand.
ASI is also the brand that people should be the most wary of when looking to buy, including from these boards. I have seen several ASI 4x20 sold on TDH that are the wrong scope. If the photo's aren't great or look 'arty' with the features I have described not easily visible then you could be looking at the wrong model. People selling the correct model will always use a decent shot, side on that clearly displays the proper features and the infinity symbol. It is important that you look for scopes by their type and features, not the brand. Just because you have found a source for an old ASI does not mean it is the right ASI, you could end up spending a lot of money for something incorrect. Remember that 'Vintage' is just the salesmans way of telling you you're buying an old piece of junk. A new 4 x 20 scope costs about £10 and are of comparable quality to these old scopes so you shouldn't be paying more than that for the incorrect 'vintage scope'. You have been warned!

This variant belongs to Lonepigeon. Note that there is no full stop after the 'I' of ASI and that the 'I' sits exactly centrally over the zero in 4 x 20. The sheen and finish of this eyepiece is identical to the Sussex Armoury Type 1(b) posted lower down. I would expect they were of the same time or batch. Photo reproduced with permission

Hunter 4x20 Scope.
I’ve seen these in both type 2 and type 3. Hunter scopes come with Type A mounts. Difficult to find info on this brand due to the association of the word 'Hunter' with the word 'Scope'. I believe it is most likely that this is the brand used on the real props. See further down.

Jason 4x20 Scope.
The elusive Jason scope. It was very hard to find information about this scope so it seems to me to be the rarest. A picture of one can be found in the gallery of the ROTJ hero prop. Difficult to see from that single picture but the eyepiece definition looks quite good so I think this may be a type 2.
Jason scopes are in fact Jason/Empire formerly of Kansas City, Missouri. It appears they stopped trading circa 1985 and may have been bought out or taken over by Bushnell (unconfirmed). The only definite information I have been able to find thus far is on a line of scopes that this company imported from Japan between 1969 and 1971. The scope we are interested in is not contained in the list of scopes I have found for those dates. As this is now confirmed as an American brand no doubt I will have great difficulty acquiring one so if any of us are going to see this model it will most likely be someone in North America (anyone got one then let me know!). The Jason scopes all seem to apply a code suffix to the scope using a three digit number e.g. 'Model 963' etc so the correct model of Jason will doubtless have a similar code. This company seems primarily to have been concerned in the sale of Binoculars, spotting scopes and telescopes all of which were (apparently) imported from Japan. The search continues.

Milbro 4x20 Scope.
I found Milbro in types 1 and 3. All the Milbro I have seen appeared to be in their original condition and all came with type A rings (one came with type B). These were quite common after ASI.

As per all type 3 scopes the locking ring is incorrect and would need to be swapped out. Photo reproduced with permission of Lonepigeon.

Note top left on the top page. Model 204 is almost the same as our boy (in fact it is 100% identical to a version of the Original Model 7 4x20 used some other SW props). I would guess that this 204 is either the direct predecessor or successor to our friend in the Rhino brand but that they were probably known by the same model number as the entry level scope. I Can't be sure of course.
Sussex Armoury 4x20 Scope.
These are known to come in type 1 and type 2. Sussex Armoury went into receivership on February 2nd 1982 and so may not have had time to produce the later models if they were trying to liquidate stock. Sussex Armoury only come with type C mounts.

The font used on this type 2 is apparently the same as the type 2 Hunter (and type 3 - above). This means that Sussex sold this (general) model of scope with four different types of branding (see below).

Webley and Scott 4x20
This is clearly an exceptionally rare scope. I found only one and this scope represents the first and only time I have seen one. In addition I have never heard others reference Webley as having made this model so I believe this is going to be the first time we are aware Webley Made this model. This scope features the correct infinity symbol we all know. The one pictured came with a type C mount fitted as is the case with all Sussex Armoury scopes too.

Other undiscovered brands?
You might think this part has been researched to death but I only found the Webley in August of 2013 and I'd never heard the correct model mentioned or referenced before. A lot of research has been done by others on this part by others before me but I did half expect to find it: why?
ASI and Milbro both do 4x15 versions of this scope with infinity symbol and I think it has long been known that they both do the 4x20 even if less widely known of the Milbro. Webley do the same 4x15 infinity scope so it seemed a natural progression for the Webley 4x20 to exist and (eventually) it did. At least two other brands do the same 4x15 infinity scope and they are KASSNAR amd 'World Famous'. I have also seen KASSNAR 4x20 albeit not this one. I wouldn't be surprised if there's a correct infinity KASSNAR 4x20 and WF out there. It's not an unreasonable leap to make. KASSNAR also available in UK in 1970s.
Could these brands be out there too?
Which brand was actually used?
Well the honest truth is that we may well never know. This section contains much subjectivity and some reasoning on my part. It is important to remember that the same type of scope with different branding are the same thing and that the scope is weathered on both versions of the prop so it really doesn't matter; at some point the similarities have to end. However close we get we will only ever be holding replications or copies of the screen original.
For ESB it is my opinion the evidence points most strongly to the Hunter:
Available in the UK to the UK based Bapty in the 1970s. Comes in Type 2 with plastic eyepiece. Comes with type A Hero rings. If Milbro made a type 2 (and I don't know that they did) then they would also be a strong candidate. I simply don't beleive that the prop builders will have gone to the time and trouble of unscrewing and then reassembling another brand (say an ASI) when a brand (Hunter) was ready to go unaltered.
For ROTJ it is harder to speculate as I know not where the prop was made. If Bapty then see above. If ILM then possibly the Jason as a US brand and if it definitely comes with type A rings although I beleive it possible that the Hero prop scope could be from the disassembled ESB EE3 prop and therefore Hunter again.
Whilst I can't rule out any one brand that comes in a type 2 completely I can assert that in my opinion the most likely candidate for both Hero props is the Hunter 4x20! There's a certain poetic justice to the Hunter brand being picked for a Bounty 'Hunter'. I know one thing: when I assemble my final ESB replica using my real Webley, MPP and all the other real parts I have acquired I won't be using an ASI that I have modified, I'll be using a Hunter, in original type 2 with original type a hero rings (until definitive evidence of another brand is shown).
Availability and sources:
I'm in the UK and my hunt is based on that. I'm in the country of origin so I have it easy and have found quite a few of these scopes although I don't own that many anymore. If you don't live in the UK and don't have access to the wider sources I do then price goes up and numbers available are fewer.
Ebay UK is a great source for everyone and a large number of the scopes I saw were on ebay. The issues surrounding ebay are well known. The only thing I would advise is to search often. If you miss a BIN then it's gone forever. The First Sussex I picked up was £5.00 and listed for under an hour before I snaffled it with a BIN. Keep search terms wide for those poor listings.
Gun boards and forums also a good source but if your post countlow and you chime in for an ASI then there is a good chance they'll see you coming.
Charity shops, at car boot sales and local papers. Bought two correct scopes from charity shopes for under £5. Interesting point on the latter two; I discovered that the ASI Rangemaster Air Rifle came with the 4x20 scope fitted to it and so found one for sale in the local paper. Bought whole item for £50, removed scope (type D mount), sold rifle sans scope for £40. I also saw Rangemasters with scopes fitted at car boot sales. You’ll need to be cautious as ASI sold rifles with different models of 4x20 fitted too! It would seem that ‘Anglo Spanish Imports’ imported from El Gamo of Spain and the same scope can also be found on vintage El Gamo Rangemaster Rifles. In the case of El Gamo the scope is unbranded but is the same. The ASI Rangemaster rifle is effectively a re branded El Gamo rangemaster; a great source for vintage scopes.
This is a picture of an ASI Rangemaster that sold in late 2012 through Gunstar for £120, the box may have pushed the price up. Looks to be a type 2 with type D:
A Gamo Rangemaster that sold for £60. Unbranded but identical scope (looks to be type 2 with type D).

Scope Ring sources (other scopes)
Type A Hero rings and tall feet. If they don't come on the scope complete as in the Hunter, Milbro or Rhino then the single biggest source is the Webley and Scott 4x15 in a variety of models. Pictured here are two different models of Webley; One is the infinity symbol and t'other different symbol but both originally came with type A. Never paid much more than £20 for a Webley 4x15. Once I'd swapped the mounts out and sold it on I didn't lose out by much and in a couple of case I made a profit on them!
Type A Hero Rings = Webley 4x15!
Type B Rings with short feet – You'll find these on Nikko Stirling Mountie 4x20 (variety of models), Nikko Stirling Cadet 4x15, Original Model 7 4x20 (rare in it's own right - used on other SW props. Do yourself a favour and sell it on whole if you find one), Original Model 9 4x20 among others.
Type C mount for ROTJ stunt – Up to £15. Seen bucket loads of these. Just look for old 4x15s in a variety of brands. Easy find. Once you sell the scope on you won't pay more than £5 for these.
Live the dream.
