This very scarce Colt Hartford-English Dragoon Revolver is one of just approximately 700 manufactured circa 1853 at Colt's London Armory using parts from the Colt Armory in Hartford. This revolver has the Second Model Dragoon style squareback trigger guard. Colt cleared out much of its older inventory of parts when it began shipping Dragoon components to London, but it is estimated that only ten with Second Model components have survived, and of those, half are engraved. It was engraved in London with scroll engraving, floral accents around many of the screws, and floral patterns on the bottom of the loading lever arm and the recoil shield. It is documented in the included copy of a factory letter as one of 67 shipped to J.C. Grubb in Philadelphia on September 2, 1861. It is also featured on the cover of the February 1971 issue of Guns magazine and shown in the article "'Case' History of Colt...Part 1" by James E. Serven. Colt's Dragoons were evidently not popular in England, but they are well-known to have seen significant use during the American Civil War by cavalry in both the North and South. Colt likely saw an opportunity to sell off the remaining Dragoon revolvers with the outbreak of the war and used it to clear their inventory of obsolete revolvers. The barrel and cylinder have London "crown/GP" and "crown/V" proof and view marks. The top barrel flat is roll-stamped with the legend: "{ADDRESS SAML COLT NEW-YORK CITY}" reading toward the breech. "COLTS/PATENT" is engraved rather than roll-stamped on the left side of the frame. The cylinder is roll-engraved with the Texas Ranger and Indian battle scene and "MODEL U.S.M.R./COLT'S PATENT." The matching serial number is marked on the loading lever, wedge, arbor, cylinder, barrel, frame, trigger guard, and butt. It comes in a fitted, English style case with a James Dixon & Sons flask, L-shaped combination screwdriver/nipple wrench, Eley cap tin, dual cavity ball/bullet mold, and a cartridge pack.
