[quote=“Tony Williams”]Nice story! :-D
I have my case listed as a Limbo but I have no evidence for that, someone must have told me - so it could be wrong. Certainly it is very much smaller than any case based on the 3" 20cwt/77mm would be: the rim diameter is only about 77mm.[/quote]
Do you know anything about the 3 inch 20 cwt or 77mm Naval guns? I joined the RN in 1959 and cannot recall having come across them. These cases are interesting in that they show the “parentage” of the A/S 10 cartridge.
