Large blunderbusses like this one inevitably evoke the Age of Sail and pirates. These guns were mounted in swivel mounts and could be positioned in various places on a ship for close action and could also be used for signaling. The lock is marked "COOPER/LONDON." We have previously seen similar swivel guns with Cooper & Goodman markings. Cooper & Goodman were located on Woodcock Street in Birmingham in 1850 and made Pattern 1853 "Enfield" rifles. Charles Henry Cooper was the successor to the company in 1888. In the late 19th century, flintlocks were still being used in parts of Asia and Africa where England still had colonial interests and where pirates remained a threat. The barrel has Birmingham proofs flanking the "12" bore marking and flares out to around 2 inches at the muzzle. The furniture is brass. The stock has a hole for fitting the gun to a swivel mount on a boat.

Fine with attractive aged patina on the brass, mottled gray and brown patina on the lock, and general mild overall wear. The stock is also fine and has mild dings and scratches and some minor cracks at the breech. Mechanically fine.
