Late WWII Nazi pistol produced for the Waffenamt (German Army Weapons Agency) at the CZ factory in Prague, probably around 1944. The Modell 27 was adopted by the Czech military in 1927 and continued in production until after the war. Waa76 is the Third Reich inspection mark for the CZ factory. The eagle-over-swastika stamp is a Nazi military test proof. "fnh" was the German ordinance code for the Prague factory where it was produced. Those obviously date it during the war after German conquest of Czechoslovakia, but before the Russkies kicked them out in 1945. And the serial number suggests late in the war, because they continued to make these post-war, starting with the serial number 476XXX.
