Gentlemens:
There was a Davidson scope that was sometimes seen on Fraser rifles, in fact I gather there was a business relationship. It was a straight tube scope with a telescoping eye piece that slid into the main tube upon recoil. Said eyepiece had a bulbous "donut" of sorts around it to protect the eye.
It is this donut that I am in need of information on. I have a scope to work on that is missing this protector and I need to fabricate a replacement. Do any of you good folk have one that you could measure? I see from pictures that they tend to vary a bit in shape, but any information would be welcome.
It would be good to know just how it was affixed to the tube, and what it was made of. My guess is Gutta Percha, but I have never seen one or even a color photo of one.
Any help would be much appreciated.
Best to all,
Glenn Fewless
