We were discussing on the handgun forum a luger two of us saw at a okla city gun show, it was a 1920 over 1920 with a DWM toggle and a russian rebuild mark? a X on the forward left receiver side, it was a mixed no. and had a cheap looking pair of wood grips, it also had what appeared to be Wiemar proofs[drop wing eagle] under heavy black matt finish, would this be one of the recent russian imports and how common is a double 1920, thanks
