My Grandad; devoted petrolhead & despatch rider for the British Army during WW2.
Here he is looking mean & moody on his ride. Looks like a BSA M20?
Note the George Regina crest of King George VI on the tank.
After the war he opened an engine shop and drove a decommissioned Willys Jeep around with the name of his business on the side. You didn't see too many of those around in Blackpool in the 40's. He was quite a character.
