This 1850s Lancaster rifle features Charles Lancaster's patented oval bore rifling which both produced excellent accuracy and was easier to load and clean thanks to the lack of grooves cut into the bore. The Damascus barrels have a flat raised rib with a beaded blade front sight and flat folding three-leaf rear sight graduated for 100, 200, and 300 yards. The breech plugs have scroll and border engraving on the rib section, platinum bands and plugs, and matching serial numbers on the hooks. The underside of the barrels have the matching serial number and London proof and view marks flaking Lancaster's "CL" maker's mark in the breech section and "CHARLES LANCASTER 154 NEW BOND ST. LONDON" and "PATENT SMOOTH BORED RIFLE" on respective barrels between the rear ramrod pipes. The standing breech is grooved for point blank sighting and has fine scroll and floral engraving. The flat, scroll engraved locks are signed "C. LANCASTER/LONDON" and have sliding safeties ahead of the hammers. The trigger guard has detailed a scene of two sparring stags engraved on the bow, scroll engraving ahead and behind the scene, the serial number on the tang, and a knurled grip extension at the rear. The round patch box lid also has a scene with a herd of deer, and the finial has fine scroll and floral engraving. The trigger plate and ramrod entry pipe have very ornate pineapple finials, and the checkered buttplate has a detailed dog, scrolls, and floral patterns on the tang. Attractive walnut half-stock has multi-point checkering on the forend and wrist, the matching serial number on each side of the ramrod channel in the forend, an oval cheek piece, and a blank silver oval escutcheon and a sling stud on the bottom of the butt, and the corresponding sling eye is on the mid ramrod pipe. The ramrod has a brass front tip and a ball puller with threaded cover on the rear. Included with the rifle is an old, hand-written letter labeled "Lancasters/Directions" and stamped "LANCASTERS/151 NEW BOND ST./LONDON/GUN MAKERS" stating "A felt adding should be placed between the powder and the ball. The ball should not be rammed down hard so as to crush the powder. The mould should never be dipped in water. a greased linen patch should always be used with the ball. The powder flask and measure are set to the proper charge. Coarse powder only should be used." The relined takedown case has a Charles Lancaster trade label inside the lid and a variety of loading and maintenance equipment of mixed ages including an original leather wrapped Hawksley powder flask numbered to the gun.

Fine with over half of the older refurbished brown finish and distinct Damascus patterns remaining on the barrels, 50% original case colors (strongest on the patch box), 60% original blue finish on the trigger guard, patches of mild pitting, crisp engraving, and mild overall war mostly from age and storage. The stock is very fine and has crisp checkering, a few spots of wear mainly on the forend, and smooth oiled finish. Mechanically excellent. The case has mild wear on the exterior, minimal wear on the newer lining, and some staining on the trade label. The accessories are fine or better overall and generally have light wear. This is a very attractive Charles Lancaster double barrel sporting rifle certainly fit for an English gentleman.
