Help with ID and parts

John, Judging by the serial on frame and lack of markings on the chamber, this sounds like a 1906 Commerical. Since the serial numbers on the small parts don't match, probably just a shooter. Does pistol also have a grip safety? If so, this should be numbered under the left grip plate. Is yours a 7.65mm with a 4&3/4" barrel or a 9mm x 4"? TH
