Amazing info Rafalfett, as always!!!!!!!! Thank you so much!!!!!!

Now I'm a bit dense but am I correct in the understanding here that the perspex block itself is supposed to be internally lit up by the GoW lights?
Just ordered some of these bulbs to do a test. Also, from your pic of the ESB RF top that's partly hanging out, Rafalfett, it looks like there is a 1mm or so section of aluminium on the inside of the RF block?

That's great news!
I noticed too that there's something under the perspex block, and I assumed that its purpose is to let the perspex block to sit at a specific distance in the RF housing. Here is a drawing (a WiP of my new RF templates that will be awailable with my RWH v2 helmet templates) that shows with approximation these 'spacers':

The Rangefinder casing thickness is around 2mm and the spacers are 1mm for the ESB and 1.5mm for the ROTJ. The image is an interpretation of the movie era RF setup for both ESB and ROTJ.
RafalFett, you are brilliant and I can verify that you are indeed correct on both the wheat lamps and the 2 part Perspex. There are three wheat lamps in the perspex in addition to the two red LEDs that everyone already knows about.
The metal is not a spacer, but serves to reflect the light of the wheat bulbs. Also, it covers the entire top of the perspex.
The perspex is simply pressure fit into the rangefinder (with doublesided tape holiding it in place). The reason you are seeing a difference between the RotJ and the ESB is most likely due to the perspex not having been cut exactly the same thickness from helmet to helmet.
I understand! It's something like this:

The foil's thickness is around 0.33mm.
That's it. So on the PP2 the aluminium foil isn't there...
Because you have the wires running into the Perspex block powering the grain of wheat bulbs, when the adhesive strip fails, as seen on the ESB hero, the only thing preventing the block falling out are those wires. This is why the narrow end of the block has slipped out, revealing that aluminium backing sheet.
