Both of these revolvers were assembled at Colt's London factory in 1853 from parts manufactured at the Hartford factory. Only 700 of these revolvers were manufactured. These two are just a few serial numbers apart (49 and 52), and each features related but different English engraving. Both revolvers feature "COLT'S PATENT" in banners on the sides of the frame and primarily traditional English scroll and floral engraving patterns. The first revolver's back strap has traces of an inscription executed with dots that began with "Lie" (lieutenant) and ended in "ves," and the frame and back strap are cut for a shoulder stock. Both revolvers have blade front sights, the "{ADDRESS SAML COLT NEW-YORK CITY}" barrel address, London proof and view marks, the Ranger and Indian battle scene and "U.S.M.R." and "COLT'S PATENT" markings on the cylinders, and are all matching with the exception of the wedge of the second revolver (marked "179"). The second revolver has a six-pointed star on the right side of the trigger guard (used later by Colt on repaired arms) and a small diamond shaped marking on the left side at the front. The rare possibly unique period case is fitted to the revolvers and also has a loading and cleaning label inside the lid, a cleaning rod, a bore brush attachment (not compatible with the rod), two Eley Bros. cap tins, ornate key, extra mainspring, brass dual cavity bullet mold, two L-shaped combination tools, an oiler, and a James Dixon & Sons powder flask.

Fine with crisp engraving, 70% original silver plating on the grip frame with loss mainly on the back strap where the inscription was removed, 25% of the original blue finish remaining mainly concentrated on the left side of the barrel lug, traces of original case colors on the frame, 40% of the faded original case colors remaining on the hammer, mostly smooth gray and brown patina on the balance, mild pitting mainly on the barrel, flattened safety pins, distinct primary markings, some fading of the cylinder markings but mostly distinct scene, and general mild overall wear. The grip is also fine and retains the vast majority of the varnish and has some scrapes and dings, slight gaps between the left panel and butt, and minor edge wear. Mechanically fine. The relined case and accessories are generally very good, with the flask in excellent condition, and have minor storage related wear.

As described in "A."

The grip is also fine and has most of the varnish remaining, small dings and scratches, and light edge wear. Mechanically fine.
