I found this really very strange little camera recently. I have absolutely no idea what it might be.
It appears to have been produced as a working camera, as it has a rudimentary winding mechanism for whatever kind of light sensitive paper went inside, and a viewfinder, and a hole in the back to check the status of the film. There is no glass lens, just a lead front with a hole in the middle, though there are slots which make it look like there was something else attached to the front at one point.
If anybody knows what it is I would be very interested to hear about it.
