This is a fine, solid representative example of a U.S. Colt Cavalry Model Single Action Army. The accompanying factory letter lists this revolver as one of 200 SAAs sold to the U.S. government and delivered to the U.S. Government Inspector at the Colt plant on February 3, 1891. The 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 "RAC" 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. The ejector rod has a bullseye head. A "K" Colt inspection mark is stamped below the serial number on the trigger guard and back strap. "P" proofmarks 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.
