This is a Zorki C encased in what looks like a almost 4-5mm steel body. The purpose of this camera still remains unclear, although the person I bought it from had stated it is for attachment to a telescope or a medical equipment.

The back plate can be taken off by unscrewing 2 large bolts and swiveling them to the side. The frame mask is very unusual it is 14x14mm. The camera looks like it that it still takes 35mm perforated film but the film advance teeth were ground off except for 2 on top and bottom of it, maybe for the purpose of only advancing it 14mm..

The front lens opening is just a large rounded rectangular gaping hole with holes for 6 screws around it for mounting to some kind of device.
