was given a beautiful Auricon tripod from a friend and went on ebay and found the matching 16mm camera. It arrived but had no reflex viewfinder. I found a picture of the same or similar lens on a bolex camera on ebay. I would like to buy a compatible viewfinder. I hope to actually use the camera but it is mostly for effect in my editing studio. The exact lens model markings read: SOM BERTHIOT Paris Pan-Cinor 1:2 f = 17 a 85 B t6 S.G.D.G. . The best I can tell is that it uses a split prism mechanism that has a threaded ring coming off the base of the lens at a slight angle. I am looking to buy either a viewfinder of a whole lens. thanks
P.S. I have a picture of lens but it is too large to upload. I can email it if you would like to see it.
