Fuze, nose, T&P, No.221B MKI, GB

[Mrfuze]

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.
Enjoy!

Superb cutaway Mrfuze, but are you sure it's a 221B Mk 1?

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
