Gustave Young is believed to have become Colt's primary engraving contractor after that position was created in 1855. He was already engraving for Colt by 1854 based on the famous "Young lists" of revolvers engraved by his shop that year. The engraving on this revolver is very similar to the engraving on the "No. 2" engraved SN. 90389 Colt Model 1849 Pocket from the Young list dated June 3, 1854, sold by Rock Island Auction in May 2022. This revolver was also manufactured in 1854 and has the classic Germanic scroll engraving associated with Gustave Young and his shop. The fan patterns, dog head on the left side of the barrel, "Saml Colt" barrel inscription, and "COLTS/PATENT" frame inscription are all features associated with Young. The engraving covers nearly the rear half of the barrel, the flat sides of the loading lever, all of the fame, most of the hammer (classic wolf's head motif), and sections of the grip frame. The revolver also has a smooth, one-piece, antique ivory grip. Matching serial numbers are on the loading lever, barrel, arbor pin, five-shot cylinder, frame, trigger guard, and back strap. The factory "dot" special finishing marking is by the lower serial numbers. The wedge is blank.
