I didn't mean to take it home, especially not on the bus.
I hadn't recognized it for what it was, so I'd put it in my rucksack thinking it was scrap metal.
After cleaned it at home and removed the encrusted mud with a hammer, I suddenly felt a little uneasy holding it in my hand.
Some quick research then confirmed it as a High explosive - two inch - World War Two - British Army mortar bomb.
With it's ability to explode, even after seventy or so years still remaining, it had to be disposed of.
I don't have it any more, and wouldn't recommend taking one home. They don't make good company these explosive devices
