Originally a Cavalry Model, this revolver was overhauled by Colt to Artillery Model configuration. These arms 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 David F. Clark sub-inspected frame (54501) dates to 1880. The trigger guard (82834) and back strap (73630) fall into the David F. Clark sub-inspected era. The unnumbered cylinder has a "P" proof mark along with the Colt "K" inspection mark on the rear face. The barrel has a "P" proof mark and Orville W. Ainsworth's sub-inspector "A" initial along with the serial number "8200" and the one-line Hartford address. The butt of the grip has Rinaldo A. Carr's sub-inspected initials "RAC." The right side of the grip has a script letter "RAC" cartouche. The left side of the frame is stamped with the three-line patent dates marking followed by "U.S." Provenance: The Thomas Whiteman Collection
