Nice one Ben, very good. I wonder who got the other one. I understand it was a slightly different type.

Nice to see a Mk I (or IA) Rigid Limpet. Development started on them in 1941 as a replacement for the MD1 versions. Early experiments were done at SOE Station IX (Welwyn) and Portsmouth dockyard but the substantial progress was acheived at Station XII (Aston House). There are a number of experimental variations but the first 'production' type had 10 magnets quickly replaced by the six magnet version (the Mark I) when the Alcomax magnet came along. The Mark IA differs from the Mark I simply by the addition of a rubber sealing washer in the filling cap. The 'more common' Mark II has a well underneath to take an anti-removal switch. A Mark III was designed at the end of 1943 which had a large filler cap at each end. Development of the Mark III ceased in 1944 and I don't believe any were issued to the field. Just 33,500 of the British Rigid Limpet were manufactured during the war. I say British because the Americans made a copy for use by OSS, it had a plastic body and frame.
