What gun developed in Nazi Germany and used in WWII did the M56 submachine gun clone?
M56 Submachine gun The M56 submachine gun is a Yugoslavian submachine gun chambered in 7.62×25mm Tokarev, designed for use with the Yugoslav People's Army. Initially a state-funded product, it was later produced by Zastava Arms and saw use in a number of conflicts following the breakup of former Yugoslavia. The M56 is a clone of the MP 40 submachine gun used by Nazi Germany, easily distinguished from the MP 40 by its increased length and curved magazine.
New Nambu M66 The New Nambu M65/M66 is a submachine gun of post-World War II Japanese origin manufactured by Shin-Chuō Industries (Formerly Nambu Arms Manufacturing Company; now Minebea). It is a blowback, open-bolt configured weapon chambered in the 9×19mm Parabellum round fed from a thirty-round magazine. The firearm was only tested and produced under trials for the considered replacement of the aging M3 submachine gun that was supplied by the United States Military during the formation of the National Police Reserve after the war.
