7.63 Mauser. 5.5" tapered round barrel. SN: 316648. Blued finish, fire blued trigger, safety, extractor and sight elevator, bright bolt and hammer, 34-groove hardwood grips. Single action semi-automatic pistol with fixed magazine, detachable shoulder stock-holster, Tanget rear sight graduated to 1,000 meters, a fixed blade front sight and a split ring lanyard loop in the butt. Right rear of frame is marked WAFFENFABRIK MAUSER/OBERNDORF A. NECKAR with the top of the chamber marked WAFFENFABRIK/ MAUSER/OBERNDORF A.N. The left side of the chamber bears a {Crown}/U Imperial German proof mark and the right side of the chamber {Crown}/{Gothic Letter} Imperial German Army acceptance mark. The full serial number 316648 is present on the left angled breech of the chamber, on the rear of the receiver and on the rear of the grip frame. The balance of the parts, including the hammer, bolt and interior of the magazine floor plate have the partial number 648, as do the interiors of both grip panels. In all cases, with the exception of the grips and the bolt, the last number, "8", is over-stamped over another number, clearly a factory error being fixed by "force matching" the gun. The pistol is accompanied by a wood holster stock with the matching number 648 on the attachment collar, but no military acceptance marks.
