Harry, what type of fuzes are they in the photo? I always thought the 3.7" used the No. 199 Fuze, but they are clearly different from the No. 199.
I would like to find a complete inert 3.7" AA Round or even a case, but I can't find one anywhere. How much would a case cost? I imagine that a complete round ( case, primer, proj, fuze) would be into triple figures.
The British cases above 18 or 25 Pounder from both wars seem to be very hard to find. I would also like examples of the 4", 4.5" and 4.7" Naval cases, but also, can't find them anywhere, not even the modern 4.5" cases.
