This revolver was likely manufactured and engraved around 1865 and has the "IE" marking by the main serial number locations used by the factory on revolvers designated for engraving and special grips. The exact year is not clear due to conflicting information on the production dates of this model which is now believed to have been manufactured in 1865-1872. It features the classic "vine scroll" patterns found on the late Colt percussion revolvers on the barrel, loading lever, frame, and grip straps. The hammer has the wolf head design and "COLTS PATENT" hand engraved on the left side of the frame like many Gustave Young engraved revolvers. The engraving patterns and marking very closely match the engraved Pocket Navy shown on page 152 of "The Book of Colt Engraving" by Wilson. The revolver is finished with silver on the barrel and grip straps, gold on the loading lever, cylinder, and hammer; and case colors on the frame. The grip has Justice seated and an eagle with arrows by her side carved on the left side. The barrel has a dovetailed blade front sight and "ADDRESS SAML COLT NEW YORK U.S. AMERICA," and the left side of the trigger guard has "36 CAL." There is a "S" marking behind the trigger guard bow on the front strap, and there is a "4" in the hammer well.

Fine with 80% original silver plating on the barrel with aged patina, traces original gold on the cylinder, 75% plus bright original gold on the hammer and loading lever, traces of original silver on the grip straps, aged patina on the exposed brass, smooth gray patina on most of the frame and cylinder, dings concentrated on the cylinder and recoil shield, generally crisp markings aside from the cylinder scene, and crisp engraving. The grip is fine and has age cracks, attractive aged tones and natural grain, and mild wear. Mechanically fine. This is a very attractive classic Colt with classic vine scroll engraving and a distinctive carved grip.
