After I found them the word get about, People telling me stories about them from the war . One local farmhand was working in the field came across one and it blew the bottom part of his leg off, And I met A gentleman On ,my-son-in-law’s farm not far from the field where I found them , Had one stuck in a Cultivate ,everyone told him they was armless as he was trying to get it out it went off and blew his wrist off and he had an artificial hand.10 llb flash and smoke practice bombs. Both used, both safe. That part is cast iron with a brass rod through it, which is the firing pin if you like. Police took one off me when I took it to school. Used to close the local beet factory if one ended up there. Still find them.
