Lol. Same here. First thing I thought was 'meh, I was doing that in the Armstrong Patents apprentice shed when I was 16'. I've still got some of the tools I made then. And the toolbox I made to keep them in.
I've been at Armstrongs(Bollhoff now) for 25 years. It's a small world but I wouldn't like to paint it. Filing mandrels is very boring now
I wasn't really trying again but I'll have a guess at Bev Minster. After that I've given up. If I'm right I'll pm you my address for the prize.
