In Germany, the STEN models “Potsdam” and “Neumünster” were manufactured during WW II. In late 1944, the Mauser works in Germany secretly started manufacturing copies of British Mk II Sten, apparently for diversion and sabotage purposes. These weapons were intended to duplicate the British original as closely as possible, right down to the markings. The series was referred to as the „Gerät Potsdam“ and approximately 28,000 weapons were made. Also, during WW II some resistance groups in German-occupied countries (DNK, FRA, NOR, POL) produced significant numbers of Stens.
