Nigel. The infantory was based on records of shipments delivered since 1982. These came from four countries. Prior to that the amount of AR180's/M1's/M50's was counted in the low hundreds.Colonel Gadaffi sumitted his records of supply to the British early last year. Allowing for training purposes and use, all of the Semtex H was accounted for.I imagine in time the information will become public knowledge.As to the estimates Nigel these were very close, dam close. There were allowances for dumps which could not be located due to the quartermaster death or such like.Regarding the amounts allowed here, this too proved to come in under the governments expections.So have peace of mind that tonight in a disused quarry there is a very heavy brick of setting concrete.
