The Spz (apparently an abbreviation of Spielzeug) was a family of German assault rifles that was in the planning stage during the latter days of Nazi Germany.^[1]

Overview

The overall weapon is largely made up from Sten MKII submachine gun components (which the Germans copied as Gerät Potsdam), most notably the receiver and buttstock. The magazine and magazine release are from the StG-44, and so were the barrel blanks. There were three variants designed. The Spz-l (lange Bauart, long variant) used a conventional layout with separate pistol grip, while in the Spz-kr (kurze Bauart mit Regler für Serienfeuer, short model with burst-fire switch) and Spz-kv (kurze Bauart mit Verschlußzündung, striker-fired short model) the magazine itself was the pistol grip. The Spz-l and Spz-kr were hammer-fired, while the Spz-kv was striker-fired. All variants were gas-operated, had swappable barrels, and were designed for selective fire. Single-shot fire could be applied by pulling the trigger half way, while pulling the trigger further to the rear produced burst fire.^[1] This function predates the similar operation used on the present day Steyr AUG series of rifles.

There is no trace of these weapons in official Nazi documents or even in some German manufacturer's archives. Wimmersperg however had contacts with Mauser, Simson & Co, and Fokker for some of his other designs.^[1]

The gun was designed by Heinrich von Wimmersperg of Austria, who after World War II, moved to Detroit, USA. In his later years, he patented designs for car seats for infants and toddlers.^[2]
