Found this the other day. A number 121 fuze converted into a number 124 fuze. The second '1' has been over stamped with a '4' and the II has been struck out and restamped I.
Does anyone know if the No. 124 is much rarer than the 121?
The fuze list gives 125 as non issued cancelled 1939 but intro as 1938 obsolete 1948. a mkI is illustrated in the 1945 naval manual and states fitted to 2, 3 6pr CNF. will take photos at the weekend if I can.
