What might this top part with a No. 94 fuze belong to?

I was thinking 4.5 inch but don't really have a clue.

A Brit No. 94 fuze on part of a projectile which has a diameter at its base of about 100mm (roughly 4''), I've found similar pictures online but nothing that really identifies it.

Thanks for any help.

Thanks, that's fantastic!

I've been searching photos online for over a week and found nothing.
