Manufactured in 1891, this revolver is one of the U.S. Colt Cavalry Model revolvers in the serial number range 131187-140361 that were inspected by Ordnance Sub-Inspector Rinaldo A. Carr. Carr's sub-inspector "R.A.C." mark is found on the frame, barrel, cylinder, and bottom of the grip. Carr's script letter cartouche is on the right side of the grip. The left side of the grip has the correct date "1891" over "LEB" script letter cartouche. The top of the barrel has the one-line Hartford address. A "K" Colt inspection mark is stamped below the serial number on the trigger guard and back strap. "P" proof marks are stamped on the cylinder and barrel. The left side of the frame has the three-line patent dates marking followed by "U.S." Matching full or partial serial numbers are on the frame, trigger guard, back strap, cylinder, and barrel. The included copy of the factory letter confirms the current configuration (barrel length and grip not listed), as well as shipment to the U.S. government inspector at the Colt plant on 20 January 1891 in a 200 gun shipment.
