The custom engraved Colt number three Derringer with "-COLT-" in italics on top of the barrel and custom punch-dot backed scroll engraving on the barrel and frame. The back strap is inscribed "H. Mills", with a pair of smooth bird's head ivory grips. With a blue finished barrel, nickel frame, casehardened hammer and niter blue trigger. The pistol fits into a small lidded compartment inside a brass reinforced, green felt lined gamblers kit, which also contains four .41 rimfire cartridges, 2 decks of cards, one card holder, 15 carved bone dice of mixed sizes, one ebony and ivory dice cup and 200 chips (75 white, 50 yellow, 50 red and 25 green), all bearing an "M" mark on the face. "H. Mills" has not been positively identified.

Very good as custom engraved, with 80% of the original silver finish present. The barrel has turned very dark with some mild bubbling, while the frame shows a lighter, but still well artificially aged, patina. Mild wear is present on the high edges with some scattered flaking and handling marks. The visible brass shows a fine mustard color. The grips are good with some light cracks and attractive grain. The modern made custom gambler's kit is good with some warping and cracks in the wood, minor grain cracks and attractive color on the dice cup, and mild wear and stains on the other gambling equipment.
