This is a Rare vintage stereo 3D camera Heidoscop 1:4.5/5,5cm Tessar FRANKE & HEIDECKE. It uses film plate, not film. The overall condition is as photos show.
The shutter, aperture are moveable. The shutter response at Z, M stop and other speed. But I can't verify the accuracy. The focusing knob is movable but the viewfinder looks fuzzy. The string on the lens caps are not the original ones.
It is easy to see the wear, tears, rusty spots on the camera. You should consider this camera as a none functional one or a one for restoration project. Please ask me if you have any questions. ...
