"Waffenamt (WaA) was the German Army Weapons Agency. It was the centre for research and development of the Weimar Republic and later the Third Reich for ...
weapons, ammunition and army equipment to the German Reichswehr and then Wehrmacht. It was founded 8 November 1919 as Reichwaffenamt (RWA), and 5 May 1922 the name was changed to Heereswaffenamt (HWA).
The task of overseeing Germany's gigantic pre-World War II rearmament program was given to the Heeresabnahmestelle (the Army Acceptance Organization, commonly referred to as the Abnahme), a subsidiary of the Heereswaffenamt.
By 1940 the Abnahme consisted of 25,000 men in five departments in 16 inspection areas, augmented by specially selected plant personnel who were assigned to assist the Waffenamt inspectors in each manufacturing facility. Later, in the middle of 1944, approximately 8,000 of these Abnahme inspectors were "freed for service at the front"." - (en.wikipedia.org 27.06.2022)
