Nazi belt buckle gun. Invented by Louis Marquis and received a patent for a similar design in 1935. Koppelschloßpistole (belt buckle pistol) was developed by the SS-Waffenakademie at Brünn (Brno). Тhere were at least two versions for wartime use: a 2 barrel design in 7.65mm and a 4 barrel design in .22 cal or 5.6mm. The belt was intended to be issued to agents as a last-ditch self-defense weapon to avoid capture. Manufactured 12 models. But in private collections there are buckles with numbers 155 and 158.
