Cancarrier's Lost and Found Emporium.

Some long years ago, when I was young and broke, I joined the Territorial Army. I was a Signaller. 

Once, wandering about the Welsh countryside in a Land Rover, looking for a place to set up a radio I found this hammer left on a fence post. 

We needed a hammer, so I took it. 

Since the head is welded to a piece of zinc scaffolding pipe I have a suspicion that it will outlast me.
