Rare German SS Belt Buckle By Louis Marquis

This is a very rare Nazi multi-shot 5.6mm (.22 cal) belt buckle gun invented by Louis Marquis while in a WWI POW Camp and received a patent for a similar design in 1935. When activated, the cover would open up, revealing the barrels loaded with cartridges. These immediately fired on some test models or could be individually fired by the triggers.
