This revolver was manufactured in 1852 and has the classic German-American factory style engraving of Master Engraver Gustave Young, Colt's primary engraving contractor in the period. The full serial numbers on the barrel, frame, trigger guard and back strap are accompanied by a dot, which denoted factory engraving and special finishing. The engraving throughout consists of primarily acanthus scroll patterns accented by floral blooms along with a beast head on the hammer. The barrel has the stamped one-line New York address. The cylinder has the classic Naval Battle of Campeche roll scene and is marked "COLTS PATENT No 18624." The hand engraved "COLT'S/PATENT" frame marking certainly in keeping with Gustave Young's shop's extremely fine engraving from the period. Matching full serial numbers are on the barrel, frame, trigger guard back strap, loading lever and cylinder. Matching partial serial number "8624" appears on the wedge and arbor pin. The partitioned case contains a case key, Eley cap tin, double face standing arms and flags powder flask marked "COLT'S/PATENT," and blued bullet mold marked "COLT'S/PATENT" on the sprue cutter and "36B" on the right side.
