Thanks for the comments guys, I own the Williams 1 in the photo's. Jamies is a very nice example of a Williams 3, was good to meet another Williams enthusiast!
maz - yes it can do a full lock. It is unchanged from when it was a hill climb car so is probably not the best set up for the road, but I still love it. I have driven it like this for 4 years of ownership with no probs! Oh it doesn't agree with speed bumps though!! lol
