Hi Mick
Found a little bit ,which may be of use to you
The 501 is a naval base fuze ,essentially the same as the 500 but with a larger mag (* the little i have on the 500 says it is gas pressure armed)
entered service 1931 declared obsolete 1959
added note
Found the following in BR 932 Handbook On ammunition 1945 page 57
"This Fuze is for use with 12pdr to 5.25inch S.A.P shell"
I also found the attached drawing

Cartridge QF 4.7" SAP filled Trotyl (American for TNT but also used by the services at that time, before we switched to calling it TNT on projectiles). This calibre was originally transferred from the Navy for coast defence and the original SAPs were filled Lyddite and had a No 12N fuze.
