Hi, I got a camera that is unlike any camera I've seen before. I think it is custom made by Sharman Camera Works in SF, and all I could find is that they manufactured tripods. It has a Dallmeyer Kinematograph 2" F/1.9 lens (which tend to be very valuable), and an IBSOR shutter. It's quite simple in construction but very well made and in good shape. The shutter, mirror, aperture ring all seem to work great. Can anyone offer insight about this camera? Do you know what kind of film it was designed to take? The film door has a sort of advance lever that pushes a plate on springs with two sprockets. The sprockets are 28mm apart, which is an odd distance for film perforations (maybe 28mm film?). No mechanism for a spool takeup that i can see. Thanks for any insight!
