    "Nubs" on the back of the helmet. you know, inside the slots?

    Here's is what I am talking about;



    Bear with me, I might be on to something, and I might not.
    I believe they are Endodontic drills (or files, reamers, broaches, etc) used for Root canals
    This makes sense because the Borden Connector and the Dental expander are also orthodontic tools.
    look at these pics of some modern ones


    as you can see above, they have different sizes with corresponding numbers on them

    and here is one in a tooth for scale;

    this one has the numbers on the head (like on the helmet) and also has the vertical lines as opposed to the horizontal


    And look at this one!!!

    They are also called "Engine files"
    and yes, they do come in metal instead of plastic

    Oh man you are so on to something with this and it so makes sense with all the other dental equipment that they have used.

    honestly those things on the helmet look more like bike tire valve caps from an older model bike just painted up a bit

    I don't know. That would have to be one heck of a tiny valve stem


    Nathan - Nice work professor. I think you nailed it!

    Very interesting! Definitely not valve caps, they are too big. Even vintage style Woods valve caps are too big... But the dental tool makes perfect sense...

    Re: "Nubs" on the back of the helmet. you know, inside the slots?

    hey guys this looks right they do look the size of a endodontic root file size number (15 is that the number on the back) , finger plugger, barb broach ect im a dental technician (ex dental nurse), the grips look to run the parallel direction but they would have used older versions and in my time in dental (14 years) i havent seen these run parallel like in the last pic but could be a manufacturer desgin, and yep the others are orthodontic tools and appliances, the expander is what we would make for a child needing an fixed ortho or removable appliance (Quad helix,skeleton screw,arch expansion screw ect) and the borden connector sits in the handpeice coupling Nut & Connector (DCI). i was going to do a boring tutorial with me casting up helmet tusks (borden connector) out of chrome showing the process involved but havent had time at work as we have been so busy knocking up false teeth ect. ill look around and phone some dental companies see if i can track some down that the grips run downwards not accross but i would say that they changed it and the ones running down eventually were phased out as the others offered better grip. I'll have a crack at mocking one up with a across grip and turn it into a downgrip and cold cure acrylic it up.

    Wow! I was "meh" right up until this photo! Don't know if that is it or not, but the similarity is striking! Congrats on getting everyone fired up!

    I'm going to agree, I think you are on to something.

    It stands to reason that the modern models represented would have morphed from the model of Fetts. Just have to find some old drills now, haha.

    GREAT eye!! But to me, The ends of the "nubs" look rounded on the actual helmet. The actual drill versions look like they are flattened on the ends. Also, the grooves going down the sides ar of the helmet nubs ARE parallel(long ways). Does anyone have a pic of these drills with the grooves running long ways??

    I made a collage


    almost all are the ROTJ helmet, but the Bright Red ones are from the PRE-PRO

    I could not agree more looking at those and what was more than likely available in the 70's I would have to say that you are dead on. Even with the photos that you provided with the current drills some of them are not that far off.

    I also found this drawing of the reamers/files/drills;


    Granted, it's just a drawing but it gives me hope about the vertical ribs.

    Yeah the drill bits are probably ribbed that way and the files are probably ribbed the other way.

    deadland, I must admit I hadn't thought of that.
    My brain is fried from looking at pics of teeny tiny files

    apparently, it's also called a "finger plugger" or "finger spreader"

    on a side note, i also believe the real ones are also metal.

    BTW- if you do google those terms, make sure your safe search is "ON"
    LOL
