HMS "PORPOISE" ships plaque or more accurately known as a ships badge. This badge is heavy, being of considerable vintage in cast brass mounted on a hardwood base measuring 9" across. Remnants of previous paint can be seen. "PORPOISE" was the prototype of the Grampus class submarine built by Vickers of Barrow launched in 1932. She was one of six in the class seeing active service during the second world war having a specific role of mine laying. She was involved in various theatres of the war and played a key role in re-supplying the besieged Malta. Her fate was to be attacked by Japanese aircraft in the Malacca Straight in January 1945 being lost with all hands. Only one out of the six in the class survived the war, that being HMS "RORQUAL". This is a nice quality maritime collectible substantially made, unlike the alloy or epoxy resin material of more recent times.
