As I read, the earliest ones inspected by the Germans after capturing Czechoslovakia had Waffenamts WaA76, but once they started building them in earnest, none had the Waffenamts, as the concept was approved..My mid-War CZ-38 is 270,xxx Serial & has no Waffenamt, but is an experimental pistol. I say that because it is DA/SA by design & NOT DAO....The Czechs were such good gunsmiths & masters of metallurgy that the Germans accepted and deployed tens of thousands of CZ-24 Pistols without ever Waffenamting those! Once the Germans were running things, they marked the CZ-27's with WaA76.....DesertDave
