I have an old lens from a polaroid with the prontor SVS. with the help of Noah and Dean, and also through other posts (which I should have found first), I was able to disassemble it and attempt to clean it. Well, despite washing out a lot of dirt and grease, it still hangs in the open position. So my question is this; is it possible to mount this in another shutter without modifications? How standard are these designs? I should mention that I will be using tis on a monorail so larger controls and a preview lever would be ideal, but I'll take what I can get (cheap).
