The MP 3008, aka Gerät Neumünster, was one of two German efforts to copy the British Sten gun. The first was the Gerät Potsdam (“gerät” meaning device or project; basically project code name), which was a direct copy of the Sten distinguishable only by a marking details and a few differences in manufacturing processes. While 10,000 of those were being manufactured by Mauser, R&D engineer Ludwig Vorgrimmler was simplifying the Sten design even farther, resulting in the MP-3008.
This simplified design did away with the Sten’s barrel shroud, and used a vertical magazine well instead of the Sten’s distinctive horizontal mounting. These were the significant changes, although there was also a sling loop placed on the front of the magazine well and a few minor simplifications to the fire control parts. Unlike the Potsdam, significant variation can be found in the MP-3008 in the details of stock and grip design.
In a masterpiece of insane optimism, German official placed and order for literally a million MP-3008 submachine guns, which of course was completely insane. Manufacture was undertaken at a wide scattering of small shops, with guns being assembled by larger manufacturers from supplied parts. The total made is not known, but is probably in the range of 3000-5000. Some are marked with manufacturing codes from recognized factories, some with codes unknown, and some have no marking at all. This particular example is dewat made by “TJK” – an unknown factory.
