Military Reporter Camera
It seems to be a 35mm movie camera of Soviet military reporters during World War II. Possible, it is rare camera, as I didn't saw such things before.
It has spring-wound drive. Shutter speeds are 8 to 64 fps. Weight of camera is about 6 kg.
Nice item for any military museum or for personal collection, I believe.
There is not TTL viewfinder. Instead of it, there is turret with finders for
each lens.Lenses are 35mm, 50mm, 75mm.
The label says: Factory 393, 1947, Armament Ministry, USSR.
The mag is not detachable. It has two locks.
There are animation crank and device for film rewind.
