well no, not quite. Its designation is 117 R1M1. This was given to me by a friend who worked in a local engineering firm. Actually, the R stands for Rhodesia. These were being made in contravention of the embargo put in place following UDI. It worked OK for some years but someone in authority got wind of it and the firm was raided. Every effort was made to find every single fuze but my friends friend had just finished assembling this one and in the heat of the moment put it in his pocket. he later gave it to my friend (his colleague) who subsequently passed it on to me. The managing director spent some time in a small room with barred windows!
