Doryu 2-16 gun camera

You might think this is a 9mm handgun you’re looking at. Nope, it’s a 16mm still-image camera. The Japanese-based Doryu Camera Company made the these 1954 to 1956. The magnesium cartridge doesn’t discharge out the “nozzle”, it but come out the top and act as a flash for the camera and makes a large bang in the process. Doryu 2-16 models are now extremely rare and valuable and in 2001 one specimen sold for close to $25,000.
