No date, DWM, old style frame and reciever, stocklug, 3 7/8" 9mm bbl, grip safety, GESICHERT in lower position, coil mainspring, has holdopen.
The SN is 9088 with no letter, 88 on bottom of reciever "stop lug". Has mismatched toggle train & sideplate. The gun has an old refinish and the bbl blue is a little different from the rest of the gun, but has the same amount of wear. No SN on bbl, but has CN proof and bore stamp.
Looks like a 1904 ? Navy that has had the bbl and toggle replaced. Is this just a parts gun, or could this have been a postwar rebuild? I haven't seen very many 9mm bbls for the old long frame.
