12/11/18 - This is a rare Nazi era Luger that was likely put together from parts at the Krieghoff factory. After 1942, Mauser stopped producing Lugers to start P.38 production. Left over parts were then sent to Krieghoff as they used them to put together Lugers such as the Ku. This gun has two distinctly different finishes: some high polish, some duller military finish. Yet, all numbered parts are matching (#14). The magazine is 122 proofed and matching numbered to the gun. The grips are numbered to the gun, too. There is no date on the receiver but the toggle is 'byf' marked. The bore looks like the pistol has hardly been used, as does the bluing on the pistol. The hold open, rear toggle pin and firing pin are NOT numbered. The gun has at least four Eagle/N firing proofs and interestingly the firing pin is an early non-fluted with a Swiss cross on it. Under the receiver (internally) there is an HK L2 proof. All of this information leads me to conclude that the gun was put together during the late-war time period (NOT a post war PX gun) at the Krieghoff factory. It has a combination of DWM, Mauser and HK parts, but then numbered by the Germans to be all matching. A very unique Luger for the advanced collector.
