Manufactured early in 1913, the second year of production for Colt's commercial Government Model pistol with an approximate serial number range of C1900 to C5399. The included factory letter confirms the pistol's configuration, including a five inch barrel chambered for .45 caliber, blue finish, and types of grips not listed when included in a shipment of two pistols sent to the Golcher Brothers of San Francisco, California, on August 29, 1913. Features fixed oval blade front and rounded notch rear sights, a replacement blued barrel with inspector "P" stamp visible on the unpolished blued chamber hood, a smooth long trigger, flat smooth mainspring housing with lanyard loop, along with a niter blued checkered slide stop, magazine release, thumb safety, and wide hammer. The left side of the slide bears the two-line, two-block Colt address and patent markings with uncircled Rampant Colt behind the slide serrations, along with the caliber marking on the right. The frame is marked with "triangle/VP" and "R" on the left of the trigger guard, along with "GOVERNMENT MODEL" and serial number marked on the right side. Fitted with a pair of checkered "double diamond" walnut grips and a two-tone magazine with pinned baseplate. Provenance: The Charles Marx Collection
