The Schmeisser MP-28/II (another variant of markings is M.P.28.II) submachine gun is a post-WWI evolution of the first practical submachine gun, developed by same designer, the MP-18. MP-28/II was produced in limited numbers in Germany by C.G.Haenel company in Suhl, for police use; it was also produced under license in significant numbers in Belgium, by Pieper, and sold to some South African and South American countries, and also to China, Japan and Spain. MP-28/II was basically the same weapon as MP-18, with minor improvements such as added fire mode selector and tangent sight. Another difference was availability of different calibers in export models, including 7,63x25 Mauser, 7,65x22 Luger, 9x19 Parabellum, 9x23 Bergmann, 9x25 Mauser export and even an .45 ACP (11,43x25).
