Manufactured by the French company Manufacturer d'Armes des Pyrenees Francais (MAPF), the 'Unique' was a model of small calibre pistol designed for easy concealment. This one is smaller than the size of your hand. It is .65 calibre and has an 8-round magazine. The MAPF manufactured these from 1923-1945 and sold many to the German Wehrmacht during the Second World War.
