A large-frame Deane Adams and Deane five-shot double-action revolver, chambered in what appears to be .476 centerfire. Overall length is about 14 inches, with an octagon barrel of roughly 7.75 inches. The bore is fine with a few small patches of light erosion. Sights are a blade front and a small notched rear on the top strap. The barrel is marked to the firm of 50 King William Street, London Bridge, makers to Prince Albert, and carries Birmingham proofs; the frame reads Adam's Patent. Blue stands at around 90 percent, with the guard and butt cap going brown and some spotting along the barrel.

Light scroll engraving covers the frame, butt cap and trigger guard, and the butt cap hides a small compartment. The checkered grips grade fine apart from light bruising, the double action works, and an unusual left-side safety holds the hammer slightly back. This is a serious piece for a collector of early English cartridge revolvers; the seller notes they have never handled another like it.
