Thanks for the info Adrian. When you say that a new "F" was added at every refill, that presumably means that refilling was only done back at the munitions plant - and not in the field?

Again I could understand that live (refilled) shells would have been present in the ammo depot stores which, though "exploding" with the rest of the wagon loads, would show an unfired primer? These primers are "fired".
