Manufactured circa 1800-1810. The brass barrel is four stages with the bore flaring at the muzzle to nearly 1 1/4 inches, "London" in script on top, and turned moldings. The underside has a "crown/C[?]" marking. The sprung bayonet is fitted beneath the barrel, and the ramrod is housed on the left side. The engraved iron standing breech has a sighting groove. The flat beveled lock has a stepped tail and is signed “Ketland & Co.” The walnut, half length stock is fitted with engraved brass furniture including a trigger guard incorporating the bayonet release trigger on the finial. "DE" is marked behind the trigger guard tang.

Exceptionally fine with light aged patina on the brass barrel and furniture, mottled gray and brown patina on the iron, and general mild overall wear. The stock is very fine and has mild scratches and dings and a small spot of filler on both sides just behind the trigger guard bow along with a small crack at the same spot on the left. Mechanically excellent, including the bayonet mechanism.
