These innovative pistols were popular with British officers in the mid to late 19th century, particularly those in Africa and India where they were valuable as sidearms in the case of attack by either the native human population or the dangerous wildlife such as tigers and water buffalo. The barrels appear to be smoothbore, but they actually use Lancaster's patented oval bore rifling. Only around 233 of these two barrel pistols were made. This pistol has a German silver blade front sight on an integral raised base, fixed groove/notch rear sight on the top of the action, "CHARLES LANCASTER PATENT 151 NEW BOND ST LONDON" on top of the upper barrel, London proofs, "455 CF" in the left side of the concave center rib, the serial number on the lower tang, serrated rear strap, checkered figured walnut grips, and a lanyard loop on the butt.

Fine with 50% plus original blue finish, mostly brown patina on the balance, light oxidation, and some minor marks and scratches. The grips are very fine and have smooth oiled finish, crisp checkering, and light scratches and pressure marks. Mechanically fine.
