Pistol identification

[Lugerdoc]

Larry, Since Ron isn't prepared to make a "WAG" (wild ass guess), I guess that it's my turn. ASSUMEING that this pistol is unaltered, except ground stock lug, since manufacture; I would say that the grip safety/stock lug short frame, would have to be a left over WW1 Navy frame (if suffix letter is original, it may be an a or b rather than an e). The horizonal C/N proofing on the left receiver and frame, could very well been done by Kreighoff during the 1920s or early '30s. They may have also applied the C/N proofs to the TOP of the breech block and even to the LEFT side of the receiver. If your info of being in storage for many years is not correct, it's possible that the horiz. C/N proofing could be of E.German rework origin, but with the gound stock lug, I doubt that. TH
