not sure if this is the correct place but here goes, picked up a couple of things at todays ECRA meet as well as meeting some BOCN guys. First is a 1in aiming case with AIC N III as ahead stamp which I'd seen illustrated but N is naval, III is the mark so what is AIC? C could well be cordite as its would be a cordite round, I is it a Mk. No.? and so what is A? the maker? if so who? second is a 37mm 1pr case for a blank not very good condition unfortuneatley but its research has got me help with an earlier question, when did V.S.M not in a circle appear answer is it was in use in 1915 but dont know how far each side of that year. What I dont have is a drawing of the 1pr blank, any help please. Thanks.
