Manufactured in 1871 (the first year of production) this is an extremely rare version of the Colt Cloverleaf revolver with the short 1 1/2 inch octagon barrel as well as a near full coverage engraving by Master Engraver L.D. Nimschke. The revolver is identified in R.L. Wilson's "The Colt Engraving" on page 216. It is one of the few known Cloverleaf revolvers engraved by Nimschke. The octagon barrel is found only on the early 1 1/2 inch barreled examples. The engraving features floral scrollwork on a punch dot background, cross hatching, wavy line and dot borders and entwining lines. The engraving is featured on the upper barrel flats, cylinder, frame sides, top strap and back strap. The top barrel flat is marked "COLT." This marking is normally on the left barrel flat, but due to the engraving the marking was moved to the top flat. The cylinder and hammer are plated in gold, and the remaining surfaces are silver plated. It is fitted with pearl grips.
