Hi all,
Well, it's strange to me; - but dare say some of you out there can tell me all about it! It is screwed into a Mk.I 4.5" Howitzer case made by VSM. The primer looks nothing like the usual No.1 primer used in this case, and is stamped VSM Mk.G

It projects further into the case than the usual No.1 type. Have been unable to remove it so far, as in too tightly. Any information gratefully received.
Thanks in advance,
Roger.
