Wonder if anyone can interpret the various markings on the two 25 pdr shell cases that I have. These were recovered by my father in January 1946 after the very large ammo explosion that took place at the Savernake ammo railhead in Savernake Forest, Wiltshire. These shells seem to have been fired - correct? So one wonders why they, as essentially recycle/scrap material were present with the trainload of live ammo? The trains were being loaded from the dump ready for disposal in the English channel.
