So...I took apart my grandmother's 2A Autographic, cannibalized the 122mm lens, and got the shutter working. I'm gonna put it on a lensboard and see what I get with my Toyo field camera. The lens is one of the really old ones....apertures are numbered 1, 2, 3, 4 with "T" "B" 1/25th and 1/50th..the speeds seem reasonably accurate and since "B" and "T" are working, they are what I am most interested in. It's one of those lenses with a single element situated behind the aperture..so It should be interesting. So....any ideas? I'm thinking f8, f11, f16, f22......before I burn up any film, does anybody know for sure?
