Wimmersperg Spz
fire arm
The Wimmersperg Spz ("Sp" stands for STEN-pistole 'STEN pistol', "z" for zweiteilig 'made of two parts') was a family of German assault rifles that was in the planning stage during the latter days of Nazi Germany.
Overview
The overall weapon is largely made up from Sten Mk II 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 (except Spz-l). 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.
This brief starts where responsible research should: with the source description of “Wimmersperg Spz” as fire arm. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as fire arm. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jun 17, 2026. The linked authority identifier is Q8023557. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
