This Model 2 variant of the Model 1855 revolver series was manufactured in 1856 and has finely detailed acanthus scroll engraving with punch-dot backgrounds and track line borders covering approximately half of the metal surfaces that closely follows engraving on the revolvers on page 74 of "The Book of Colt Engraving" in the section covering Master Engraver Gustave Young. The engraving was executed for Colt by Gustave Young or his shop, and the hammer on this revolver has Young's signature punch dots below the spur. Each dot represented a 10 hour day of work. The hammer on this richly embellished revolver has six dots. The barrel has a post front sight, "[manicule] +COLT'S PT/1855+" and "ADDRESS COL. COLT/HARTFORD, CT USA+" on top, and the matching serial number on the bottom. The cylinder has the cabin and Indian roll engraved scene. The grip has a beautiful relief carved eagle, shield, and "LIBERTY" marked scroll motif on the left side. A similar grip motif identified as "carved at Colt's factory" appears on page 93 of "The Book of Colt Engraving." The French style casing, which is rare for the Model 1855 revolver series, is lined in red wine velvet, has brass hardware including a blank inscription plate inlaid on the exterior of the lid and contains a "COLTS/PATENT" marked two cavity brass bullet mold, combination "L" shaped tool, Eley Bro. percussion cap tin with caps, lead rounds, package of combustible envelope cartridges, and double face eagle powder flask.

Exceptionally fine, retaining 85% plus bright original blue finish with the balance a smooth brown patina. All of the cylinder scene remains. 95% original case colors remain on the hammer and loading lever. The engraving is crisp. The grip is excellent showing typical age cracking on the bottom, otherwise a highly attractive color and crisp relief carving. Mechanically excellent. The presentation case is very fine with a few hairline cracks along the grain, minor handling/storage marks, and some typical high spot wear on the lining. The accessories are excellent overall. This is a very attractive and scarce revolver most likely engraved by Gustave Young and fitted with an equally impressive relief carved eagle grip. It would be an excellent addition to any collection of antique Colt firearms. A must have for the serious Colt collector!
