These cartridges were found close to an RAF base - along the beach.
I assume that there must have been a training range on this beach.
The cartridge on the left is a .50 cal.
I cannot seem to find what the other 2 cartidges are.
The headstamps are K38 F I Z & K40 F I Z.
Does anyone know what these are? And from what aircraft they would have been used in?
