These Colt "Artillery Model" Single Action Army revolvers were brought back into service during the Spanish-American War, Filipino-American War, and Moro Rebellion. Though nicknamed "Artillery Models", they were actually issued to a variety of U.S. Army units and particularly known to have been favored for use against the Moro warriors who were known to continue fighting after being shot with the weaker .38 caliber Colt double action revolvers also in use. The revolver has mixed numbers and components typical of the Artillery variants. The frame ("132307") dates to 1890, while the trigger guard and back strap ("131499") also date to 1890. The underside of the barrel is stamped with a "P" proof and inspector initials "D.F.C." "RAC" inspector initials are found on the bottom of the frame and the bottom of the grip, and there are a few "K" inspection marks throughout. The left side of the frame has the three-line patent marking followed by "US." The grip has a faint script letter cartouche on the right side. The included factory letter confirms the original shipment to the U.S. government inspector at the Colt plant on 20 May 1890, and has additional notes that it was returned to the factory for refurbishment and reassembly in Artillery configuration and reshipped on 23 October 1895.
