This mid-19th century swivel gun has "BARNETT/LONDON" marked on the lock. The barrel is marked with London proofs. The left stock flat is marked "JW." The bore is flared right at the muzzle but measured around 14 gauge for the bore. An iron swivel mount is fitted around midway along the forend, and the right side of the butt has a "BARNETT/GUNMAKERS/LONDON" cartouche. These guns could be more readily moved around a ship's deck than an actual cannon but still provided some heavy firepower for repelling borders. They could also be used for signaling. You do not find percussion era examples very often. This impressive piece of 19th century firepower comes with a display stand to help it make a statement in your gun room.
