This is an exceptional example of a first generation Colt Single Action Army revolver that was manufactured circa 1937 with the desirable "Colt Frontier Six Shooter" barrel marking. The revolver has the Colt commercial blue finish on the barrel, ejector housing cylinder, trigger guard and back strap. The frame and loading gate are color casehardened. The trigger has a nitre blue finish and the hammer is blued with polished sides. The revolver has two-piece, black checkered hard rubber grips with the Rampant Colt trademark embossed in an oval. The hammer spur has borderless knurling. The left side of the barrel is roll-stamped with the model designation: "COLT FRONTIER SIX SHOOTER .44/40". This marking was introduced in 1919 and was utilized into the 355,900 serial number range. This revolver is one of the very last Colt Single Actions manufactured with the famous "Colt Frontier Six Shooter" markings. The top of the barrel is roll-stamped with the legend: "COLT'S PT. F.A. MFG. Co. HARTFORD CT. U.S.A." in one line. The left side of the frame is roll-stamped with the Colt three-date/two-line patent marking followed by the Rampant Colt trademark. The left front trigger guard bow is stamped with a "4" assembler's mark above the Colt "Triangle/VP" proofmark. The serial number is stamped on the bottom of the frame, the right side of the back strap and right side of the trigger guard beneath the grip. The matching serial number is scratched on the inside of both grips. All of the visible serial numbers match. The assembly number "620" is stamped on the inside of the loading gate and on the end of the right side of the frame beneath the grip.

Near new. The revolver is all original and retains 99% plus of the blue and vivid color casehardened finish. Cylinder wear is limited to very faint turn marks between the stops. The trigger guard retains nearly 100% of the blue finish while the back strap shows traces of handling wear. The vivid case colors on the frame and loading gate have a slightly frosted finish that indicates minimal handling. The grips are in excellent plus condition. The action functions perfectly. This is an outstanding example of one of the very last First Generation Colt Single Action Army revolvers with the famous "Colt Frontier Six Shooter" barrel marking.
