Has anyone got any information of the British 3 inch 12 lb HE No 1 Mk 1 warhead? It was probably in service 1945-1960ish and was fitted with a No 931 Base Fuze. The fuze worked on an induction coil principle from a contact switch on the tip of the warhead. I have a pretty poor picture of the fuze but no information on the warhead. Can anyone help?
