U.S. contract Colt Single Action Cavalry Model revolver manufactured in 1880. This revolver was inspected by Lieutenant Charles G. Morrison (CCM) and Ordnance Sub-Inspector David F. Clark (DFC) as part of the fifth and sixth contracts between Colt and the Ordnance Department for Single Action Cavalry Model revolvers. The barrel, ejector housing, cylinder, trigger guard and back strap have the Colt military blue finish. The screws and trigger are a fiery niter blue. The frame, hammer and loading gate are color casehardened. The one-piece walnut grip is oil finished. The revolver has the early "bullseye" ejector rod and "cavalry style" hammer with elongated, bordered knurling on the spur. The "U.S." property mark is stamped on the left side of the receiver. A small block "D.F.C." sub-inspection mark is stamped on the underside of the barrel, bottom of the frame above the serial number, side of the cylinder and on the right grip heel. "P" proofmarks are stamped on the underside of the barrel and side of the cylinder. The lower left side of the grip is stamped with the date "1880" above the script "CCM" final inspection mark. The lower right side of the grip is stamped with the script "DFC" sub-inspector's mark. The top of the barrel is roll-stamped with the "Style IV" address: "COLT'S PT. F.A. MFG. Co. HARTFORD CT. U.S.A." in one line. The Colt "three-line/three-date" patent marks are roll-stamped on the left side of the frame ahead of the "U.S." property mark. The assembly number "190" is stamped on the inside of the loading gate. The full serial number is visible on the bottom of the frame, trigger guard, and back strap. The partial serial number "0172" is stamped on the side of the cylinder (the ejector rod housing could not be removed to check the barrel serial number). All of the visible serial numbers match. The accompanying John Kopec gold seal letter authenticates this revolver as a new listing to Kopec's survey and concludes, "The original military blue finish and frame case-colors remain outstanding throughout this example, showing that this revolver had been well cared for throughout the years."
