Manufactured in 1889, this is a much sought after example of an acid etched panel black powder and fully factory nickel plated Colt Single Action Army revolver in 44-40 WCF. The left side of the barrel has the acid etched “COLT FRONTIER SIX SHOOTER” panel. This highly desirable etched barrel panel was officially replaced by the Colt factory in the 120,000 serial number range with the much easier to produce and larger roll-stamping. The top of the barrel has the stamped one-line Hartford address, the left side of the frame has the stamped three-line patent dates marking, and the underside of the barrel has the correct small "44" marking. The matching serial number is marked on the bottom of the frame, trigger guard, and back strap. The loading gate is marked with the assembly number "4" and it is fitted with a pair of original eagle pattern hard rubber grips.
