Manufactured in 1912 as part of the second 500-pistol block of 1911s produced for the United States Navy. Fitted with blade front and rounded notch rear sights, the two-line/two-block address and patent marks are on the left side of the replacement slide with the circled Rampant Colt behind the serrations and "MODEL OF 1911. U.S. NAVY" (with serifs) on the right side. The frame bears Walter G. Penfield's "WGP" inspector mark near the magazine catch, "UNITED STATES PROPERTY" on the front left, and "No.1752" on the reverse. Fitted with a replacement wide checkered hammer, long smooth trigger, short grip safety, smooth lanyard base mainspring housing and checkered grips with diamond patterns around the screws. The nitre blued slide stop is the only remaining correct small part. Magazine is full blue and unmarked with a pinned lanyard base, and the Later production replacement barrel is marked "COLT 45 AUTO/P" on the lower left side of the chamber.

Fine, with 40% of the original blue finish showing areas of gray and brown patina, bright edge wear and scattered spotting and handling marks. A few heavier dents are present on the back right side of the slide. The grips are fair with mild dings and a thick coat of applied varnish. Mechanically excellent.
