This is a much sought after example of an exceptional acid etched panel blackpowder Colt Single Action Army revolver in 44-40 WCF. The accompanying factory letter (copy) lists this SAA with a 4 3/4 inch barrel in .44-40 caliber, nickel finish and hard rubber grips when shipped to Hartley & Graham of New York City on March 10, 1884. The barrel has the two-line address stamped on top and the etched panel "COLT FRONTIER SIX SHOOTER" on the left side. This etched barrel panel marking was officially replaced by the Colt factory in the early 120,000 serial number range with the much easier to produce and larger roll-stamping. The left side of the frame is stamped with the three-line patent date markings, and the left side of the trigger guard is stamped "44 CF." The rear cylinder face is stamped with the letter "L." Matching serial numbers are on the frame, trigger guard, and back strap.
