This is an example of a Colt Model 1873 Cavalry revolver that was manufactured in 1890 that was originally inspected by Ordnance Sub-Inspector Rienaldo A. Carr and subsequently refurbished by Colt into an artillery model. The revolver has a military blue barrel, cylinder, trigger guard and back strap, casehardened frame, hammer and loading gate and oil-finished walnut grips. The ejector rod has the oval head adopted in 1885. In 1895, a number of U.S. Colt Cavalry Single Action Army Revolvers, such as this one, were returned to either the Colt factory or Springfield Armory where they were converted/refurbished into Artillery Models with the 5 1/2 inch barrel. This refurbishment usually resulted in a mixing of the various serial numbered parts. The barrel has the elongated block address of: "COLT'S PT. F.A. MFG. Co HARTFORD CT. U.S.A.". The left side of the frame is stamped with the Colt three-line/three-patent dates followed by "U.S.". The underside front edge of the frame is stamped with "R.A.C./131921", while the trigger guard, and back strap are both stamped with "119560". The side of the cylinder is stamped with "137124/85". The underside of the barrel and cylinder are stamped with a single "P" firing proofmark. The underside of the barrel is stamped with serial number "1297" and the sub-inspector initials of "D.F.C." for David F. Clark. The loading gate is stamped with the assembly number "648". A Colt "O" inspection mark is stamped in the hammer well. It is fitted with a set of one-piece walnut grips that are both marked with the small "R.A.C." on the underside bevel of each side.
