    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.

    3.7" projectile

    Hi Andy & Weasel

    Thanks for your comments on the rounds..


    Not a problem Andy if you need any more information just let me know.


    Hi Falcon
    The fuse in the 3.7" are No208, the 3.7" could be fitted with No117, 199, 207, 208, 209, 223 & some later ones like the L1 & L7.
    You sometime see 3.7" cases up for sale I may have a spare in my garage, but I've not seen a complete round for sale for sometime, couldn't tell you how much a case would cost I traded for most of my rounds the 2 I did buy the original marked up HE & the APCBC where both in triple figures.
    There are a couple of 3.7" cases on the auction at the moment one at 40.00 & one at 25.00
    www.specialistauctions.com/auctiondetails.php?id=1198649
    www.specialistauctions.com/auctiondetails.php?id=1198654
    The 4" is much the same as the 3.7" you do see cases now & again for sale, but projectile & complete rounds I've not seen for sale for sometime ether, I always find navy bits are hard to find, I don't know if it because they throw the case over board after firing or not. The modern 4.5" case which one is it you are after?

    If you have a spare 3.7" Case I would definitely be interested.

    I know what you say about Navy bits. On the HMS Belfast, there is a primer for the BL 6" separately loading gun used as a handle on one of the latches on the door to one of the forward turrets. I have never seen one of these anywhere else, let alone seen one for sale. It is also another bit I would like.

    There are also racks full of complete inert 4" Rounds out in the open air to rust!!

    I'm didn't even know that there were different modern 4.5" cases. I'd like any one, but the trouble is storage space for those huge cases.

    Do you know what the biggest brass cartridge case ever manufactured in the UK was? I heard there was a 6" Gun that used a case, now that would be a nice find.

    The biggest calibe British case I have reference to is a 133 x 778R for the 5.25" AA Guns Mark 1, 2 and 3. I know Germany made some really big stuff that took cases (a fair few over 300mm, up to 863 x 1300R for the WW2 Dora 80cm Railway Gun).
