Manufactured in 1856. Barrel has the New York address, the frame is marked "COLTS/PATENT/U.S.," and the cylinder has the standard naval scene. Small single letter inspector initials on several major components. Faint traces of a cartouche remain on the right side of the grip. Matching full or partial serial numbers appear on the barrel, frame, trigger guard, back strap, loading lever, cylinder, wedge, and arbor pin. The Colt "Army/Navy" revolvers were manufactured between 1855 and 1859 and fall within the 42,000-80,000 serial number range. The initial issue of the "Army/Navy" revolvers was to the 1st and 2nd Cavalry regiments. The "Army/Navy" revolvers were first used on the Texas frontier and subsequently saw wide service with federal cavalry regiments during the Civil War.

Very good, retaining traces of original blue and casehardened finishes in the protected areas with an attractive gray patina on the balance. There is a noticeable series of dings on the right side of barrel at the wedge. The grip is good with a removed cartouche lightly visible on right, high edge wear and some scattered handling marks. Mechanically excellent.
