This revolver was manufactured in 1863 and almost certainly engraved by Gustave Young's shop. They were Colt's primary engraving contractors during this period. The engraving is primarily scroll engraving with floral accents and punch dot backgrounds in his classic style, as is the wolf head motif on the hammer and the shell patterns on the back strap. "E" is marked by the main serial number locations indicating the revolver was selected by the factory for engraving. The grip is carved with a patriotic design with an eagle, flags, shield, and "E PLURIBUS UNUM" on the left and is marked with the matching serial number in the rear mortise. The revolver also features a blade front sight, the New York barrel address, Naval Battle of Campeche cylinder scene, standard patent markings, all matching serial numbers, recoil shield and back strap cut for a shoulder stock, and "4" and "44 CAL" on the left side of the trigger guard. The trigger guard also has a brass plate fitted inside the guard that holds the trigger back. The hammer sight groove is also enlarged. The lot includes a tooled brown leather holster with no visible maker's mark.
