Except that shatter is Moment and story from seller, camera has no indication about it origin. Camera only has few numbers pouched inside, presumably serial number.
The seller story such: in 90-th they bought military warehouse in Moldavia (as I remember). Warehouse was full of old military close. No weapons or other equipment. Only old military uniforms, buckles, shoes(sapogi), coats, heats, etc. On one of the shelves they found 7 cameras as shown. Probably because warehouse belong to Air force they tell me that this cameras from Russian bombers. They move all what they found to US and merely put all on eBay. I lost track of this seller. He probably still selling old military gear from USSR: “pilotki”, “gimnosterki”, “sheneli”...

No more cameras.

But camera most defiantly Russian. But the way it made and tons of grease("solidol":) I found inside.
I’m only not sure that camera was used on airplane. It was so dirty and it is very heavy - probably 5 kg(10 lb). Better suited for a tank. I was asked on few forums about this camera. Have no replays. May be someone here can put a light?
I have question to the experts who may read this post: why this camera designed only for round pictures? And why it has red glass permanently installed behind the shatter?
