References
  1. Wikipedia, “Gebrauchsmuster” ↗, years (estimate: derived from related facts): ATF quotes the marking "drgm" (Deutsches Reichs-Gebrauchsmuster); German Wikipedia: the Kaiserliches Patentamt introduced the D.R.G.M. on 1 October 1891 and products were marked D.R.G.M. "zwischen 1891 und etwa 1945" (after 1949: D.B.G.M.), so the marking limits the years 1891–1945 without dating this pistol
  2. Wikipedia, “Gebrauchsmuster” ↗, country: the D.R.G.M. was the German Reich's utility-model registration (Kaiserliches Patentamt), so a "drgm"-marked piece was registered in Germany
