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 variant, including a Lot 6 back strap ("6446") featuring a faint sub-inspector Ainsworth "A" initial. Lot 6 (5505-6516) was one of the prime groupings of SAA revolvers issued to the 7th Cavalry from Ft. Abraham Lincoln on July 2, 1874, just before the 7th's departure to the Black Hills and Custer's infamous defeat at Little Bighorn. The frame is numbered "3152" which dates to 1874 and falls in the Lot 3 serial number range of Cavalry Models issued to the 4th Cavalry. The trigger guard ("49768") dates to 1879 and has sub-inspector Henry Nettleton's "HN" initials. The revolver also has a David Clark inspected cylinder and Johnson inspected barrel.
