This is a Drill fuze No198 & 400 but has a flat base so must be for practice in setting the timing -so it seems?
The No 400 is similar to the No 198 but has a different ring filling. Both are for the Navy.
Fuze is marked : DRILL FUZE No 198 & 400 11 1944 ?3B ZW in a circle.
No 198 ^ 11 N FL 2/38 9
The base is flat , never threaded and is 62mm wide. 54mm high. Is it used for fuze setting ? It cannot fit into a shell.
