In post #46 davidd showed John Surtees with a Norvin. I have a couple of questions. First, the Vincent name on the timing chest is in script. Any thoughts on this? Second, can this photo be definitively placed as 1954 or 5? This is in aid of dating the early existence of the Lyta type short-circuit tank.
Regarding the Norvin for sale in Austria - in my experience high level pipes can get mighty warm.
