Engraved Colt Model 1878 Frontier Revolver Sent to Hartley & Graham 1883

Serial #10762, .44 WCF (.44-40), 7 1/2" barrel with a very good bore that has some dark freckling within the grooves.  This is an 1883-made revolver that has full coverage flowing New York style scrollwork engraving, and an overall dull pewter gray and plum-brown patina with some faint traces of original blue on some of the protected areas.  The hammer and trigger both have an overall plum-brown patina with thin surface freckling throughout.  The checkered hard rubber grips are in very good condition with light wear and flattening of the points throughout, as well as a chip missing from the heel of the butt on the right panel.  The lock-up is still tight, and the action is fully functional in both single and double-action.  The revolver is accompanied by a 2013-dated Colt factory letter that lists a ship date of April 6, 1883 to Hartley & Graham in New York City as one of 50 identical guns in the order.  This is a very handsome early DA Colt, with extremely nice engraving.  Antique
