This factory engraved Model 1849 Pocket was manufactured in 1856. Gustave Young's shop were the primary engravers for Colt from 1852 until the mid to late 1860s. The intricate scroll engraving, hand engraved "COLTS/PATENT" marking on the frame and hand engraved "SAML COLT" "presentation style" marking on the barrel match other Young engraved Colt revolvers from the 1850s. For example, "The Book of Colt Engraving" by R. L. Wilson includes multiple revolvers with similar dog head designs worked into the scroll patterns. The dog head on this revolver appears on the left side of the barrel lug. The hammer has Young's classic wolf/hound head motif. The cylinder has the standard stagecoach scene. Matching full or partial serial numbers appear on the barrel, frame, trigger guard, back strap, cylinder, loading lever, wedge, and arbor pin.
