My pictures were taken at Hendon, where the bomb rack sits on the ground beneath XL318, along with 21 1000lb bombs! If you've no other options Bovril, you could always go and ask them if you can have a quick measure up!!
Shirley there must be some sat around somewhere? What did the RAF do with them after the Falklands? Send them back to the scrapyard they found them in??
Lightning Andy is an engineer, maybe he'll knock a few up for you after he's finished with his batteries on wheels?
