KU Luger Twins
This video examines two consecutively numbered KU Luger pistols, identified by serial numbers Kü 42 4272 and Kü 42 4273. The 'KU' prefix is a collector mystery, with these examples featuring Mauser parts (dated 1939, codes '42' and 'byf') and Krieghoff proof marks. The leading theory suggests Mauser parts were sent to Krieghoff for assembly and subsequent Luftwaffe issue.
