Don't know what made me think of it but a bartering incident sprang to mind. When I was young, under ten, I am now over 60 I collected knives. My collection was mostly tin pen knives with tartan handles. Usually bartered for marbles. I however swapped two for a hand grenade. (The deactivated shell) Remember this was the fifties, less than 15 years after the war, followed by Suez, and Korea so war memorabilia was plentyful. My father went apesh*t when he saw it. So did the boy's father. His son and him turned up at the door looking for it's return. He had already moved a knife on so I only got one back. Mind you we both eat meals standing up for a while,
