Hi Clffa
Jim Lee put Mick on the road. He framed Micks Velocette that Mick started racing on. The JL on the lid stayed, a brilliant Thank you.
Jim was really helpful when I was trying to get eligibility for my bike. He told me he never numbered his frames because it was all about the racing & making frames helped fund that.
Look up Jim Lee on Facebook, Although it's mainly cars, Jim was a builder of fabulous race cars. It has a lot of his old friends & colleagues on there & it shows the high regard he was held in.
