This is a detail from a one-gallon flagon found in association with several chests and linstocks outside the carpenter’s cabin of the Mary Rose.
The flagon is made of oak and poplar staves and had a hinged lid. The engraving shows a large gun, which appears to have human legs where the trail would be. Some claim that, when tipped, it resembles a man holding a gun shield, a weapon that Henry VIII had taken a shine to, and of which the Mary Rose had at least eight aboard.
