The right side of the slide is marked “AUTOMATIC COLT/CALIBRE 45 RIMLESS SMOKELESS” in front of the ejection port. The left side of the slide is marked in two blocks: “PATENTED/APR. 20. 1897. SEPT. 9. 1902. DEC. 19. 1905” and “COLT’S PATENT FIRE ARMS MFG. CO./HARTFORD CONN. U.S.A.” with the circled Rampant Colt behind the serrations. The serial number is located on the left side of the frame above the trigger guard bow. The upper left trigger guard bow bears the Colt “VP” triangle proof and the lower is marked with a “1”. This gun features the earlier round checkered hammer with casehardened finish. The remainder of the gun is finished in the standard Colt high-polish blue, except for the trigger, extractor, grip screws, rear sight and magazine release, which are niter blue. The grips are checkered walnut with the small diamond pattern around the screws. Complete with an unmarked blue magazine.
