stock. This is a bring back..my girlfriends father said he relieved from. a German officer. It has the CESKA ZBROJOVKA A.S. v PRAZE 360 on top of slide. "C" arrow "Z" 360 on side plate, 360 on right frame toward muzzle, 360 on mag floor plate. Circle Z followed by 29 beneath diagonal grooves on left side, "B" stamped on frame near mag well...that is it for stampings or proofs. The dark brown wrap around grips seem to be Bakelite and they are inletted for the fixture to mount a shoulder stock..the fixture is stamped 100..the holster is dark brown leather, white stitching stamped 428 on back...both pistol and holster are in exceptional condition. Any ideas? Cone Ten
