Cannon (13A51)
This cannon was found on the seabed south east of the Great Mewstone in 2013 by the SHIPS Project team. The gun may be associated with the Mewstone Cannon Site but is far enough from that site to be from a different wreck. The gun was found on a rock ledge hidden by kelp, it is heavily concreted to the seabed and difficult to measure accurately.
