sorry if this is in the wrong forum.
Earlier while walking the dog half a mile inland from the sea at Shoeburyness near the Garrison. I found a strange item that had been dug up due to property development in the area. At first I thought it was the end of a cannon but then saw that it was infact complete in length, just cross sectioned like an explosion had pulled it apart. So my guess is now that it is a 'mini mortar' type weapon but from what age/time?
Please see attached pics, it is 10x5 inches size. Evidence of burning on the inside suggests it was a weapon although it could also be one half of a mould? It is very heavy also so presumed to be made of Iron. Chipping away at the surface reveals a very shiny material.
Any help appreciated,
