Offered here is a stunning Colt Thuer conversion Model 1860 Army revolver that was manufactured from 1869-72 with total production about 5,000. The revolver has a high polish blue finish on the barrel, cylinder, and back strap; casehardened loading lever, frame and hammer; and a silver plated brass trigger guard. The top of the barrel is roll-stamped: "-ADDRESS COL. SAML COLT NEW-YORK U.S. AMERICA-". "COLTS/PATENT" is stamped on the left side of the frame. The cylinder is roll-engraved with the Texas Navy battle scene and "COLTS PATENT". The full serial number "174986" is stamped on the frame, barrel lug, trigger guard and back strap. The partial matching serial number is "986" on the cylinder pin. The cylinder is not numbered. The rear of the cylinder has been correctly shortened to accommodate the Thuer conversion ring, and the ring has a correct script "E" on the side, which denotes the eject position. The left side of the trigger guard is stamped "44 CAL." The conversion ring has the distinctive knurled turning knob, rebounding firing pin, and ejection mechanism. The Thuer conversion was the first Colt revolver to utilize a metallic cartridge and is a scarce and historically significant revolver that is missing from many of the antique Colt arms collections. The left side of the grip has a fabulous and always desirable relief carved Mexican eagle. The partitioned rosewood case contains a blued two cavity bullet mold marked ""COLTS/PATENT" on the sprue cutter, 8 unloaded brass casings, 4 loaded cartridges, sealed package of .44 CF cartridge manufactured for W.J. Syms & Brother, loading tools and single faced "COLTS/PATENT" marked powder flask Provenance: The Mac McCroskie Collection
