    Is there any reason you want to know these rather unusual measurements?

    RM - You are not being picky. Call the shell a bomb today and tomorrow it's an open hatch on a submarine...

    Try the Pakistan Ordnance Factories web-site.

    Assume you've tried Firepower museum at Woolwich an the Imperial War Museum?

    Detailed shell dimensions of any sort are a tad thin on the ground. For 25-pr your best bet is the ammo handbook for WW2 or 1950s, but I'm not entirely sure you'll find everything you need. There are also some basic dimensions in the WW2 period Handbook for the gun. There's also a post WW2 Handbook for the gun and the ammo section in this might be the best bet. Where to find these - Clavell Library at Woolwich and maybe the Badley Library at Larkhill.

    25lbr shell bodies were forged by the RoFs so they were the only folk to have the exact dimentions. Since they were flogged off to BaESystems I doubt whether they will let you access them...

    I suggest the only quick way to solve this is to go to one of the museums that hold dummy 25 lbr shell and measure one with calipers and a pin gauge.. you need to talk to whoever is going to make this thing for you...

    Museums that I know have 25lb shells -

    Royal School of Artillery at Larkhill
    Army School of Ammunition at Kineton
    Imperial War Museum - Kennington and Duxford
    Royal Armouries - Fort Nelson Portsmouth

    also your local troop of 11 EOD may have one in their own collections...

    Hope this helps..

    Well - I would suggest you're bug*ered then... :(

    My only other suggestion is that if you can enlarge R-Ms diagram so that the width of the shell is 3.25" than everything else will be roughly in proportion..

    Pity they only used 18 pounders on the post office :roll:
