They were finding this type of stuff at the huge Didcot RAOC Base Ordnance Depot when it was being re-developed as a power station and other parts as an industrial site in the 70's. Not weapon stuff as such but mainly tentage, canopies and saddlery, cartage etc etc stuff. Presumably no one was interested then and most was presumably just turned in again after being unearthed! Strangely, hundreds of tons of sheepskins too for some reason!
