Pablo, Check out the camera store on Peace Street (I think it's Southeastern Camera), a block or so East of Glenwood Avenue. They probably have a few MP-4 mounting boards lying around, or might even have mounting adapters. The camera repair shop they have on site can also probably help. They helped me a lot a couple of years ago.

I'd like to adapt them to be used as enlarging lenses, (Leica 39mm) and was wondering if anybody knows the dimensions of the copal screw mount (seems to be 40mm) and if there's any adaptor from copal -> Leica ?
