Manufactured in 1883 per page 121 of Nigel Brown's "British Gunmakers Volume One: London". Built with blued steel barrels featuring a beaded blade front sight and a fixed rear sight on the matted solid rib, "CHARLES LANCASTER 151. NEW BOND STREET. LONDON" and "PATENT SMOOTH BORE BREECH LOADING RIFLE" marked on the left and right respectively, London black powder proofs, and chambers with a single extractor. Both barrels are proofed at "38" gauge which equates to 50 caliber, likely .500 Black Powder Express based on the measurements of the included snap caps.
