This is an exceptional example of a Colt Single Action Army revolver that was manufactured in 1884. The revolver is chambered in caliber .44-40 and has the highly desirable acid etched "COLT FRONTIER SIX SHOOTER" panel on the left side of the barrel. The revolver has the Colt commercial blue finish on the barrel, cylinder, trigger guard and back strap. The frame, hammer and loading gate have a color casehardened finish. The one-piece walnut grip is varnished with the high polish piano finish. The revolver has the oval ejector rod head. The hammer has a knurled bordered spur and cone-shaped firing pin. The top of the barrel is roll-stamped "COLT'S PT. F.A. MFG. Co. HARTFORD CT. U.S.A." in a single line. The caliber designation "44" is stamped on the underside of the barrel just in front of the frame. The left side of the frame is roll-stamped with the Colt three date/three line patent markings. "44 CF" is stamped on the left front trigger guard bow. The assembly number, "1588" is stamped on the inside of the loading gate. An "O" Colt inspection mark is stamped on the underside of the barrel behind the ejector housing stud, "L" is stamped on the rear face of the cylinder and "H" is stamped in the hammer slot above the firing pin hole. The full serial number, "103773" is stamped on the bottom of the frame, trigger guard and back strap. The partial serial number "3773" is stamped on the underside of the barrel beneath the ejector housing and on the side of the cylinder. "3773" is written in pencil in the back strap housing of the grip. All of the visible serial numbers match.
