I want to share some images of a cutaway of the commonly used No.221 B MK I powder train time & impact fuze, which was used during WW II by the British in various caliber shells.

222 Fuze

This looks to be a No 222 rather than a No 221B.

Basically it's a 221, but with the outside contoured to match the 117 and 119 fuzes.
Designed for airburst HE rounds.
Introduced in 1940 and obsolete by 1951
