Massive and Highly Desirable British Ordnance Marked Barnett Flintlock Swivel Gun Manufactured c. the 1790s to 1820s, this is a large and desirable example of a flintlock swivel gun produced by Thomas Barnett. Barnett is noted as an ordnance contractor for the British government from 1794 and for the famed East India Company from 1797. These swivel guns were most commonly fitted on the upper deck rails of ships at the time, but also saw use on the parapets of fortifications, increasing the localized firepower over that of a simple musket, while not needing a multi-man crew like larger cannons. There are London commercial proofs marked on the upper left of the barrel at the breech, while the lockplate is marked "BARNETT" at the center. There are faint British ordnance markings on the right of the stock including a broad arrow. There is a pintle attached to the forestock for mounting the gun on a ship or fortification. Includes a hardwood base for display.
