A short video I said I would do to Noel to explain the thought behind the four slots in the pit bike spinner base... (Noel if you want to put a link in the design, it might help?)

Neither did mine Nick, but as soon as a car is off the production line, owners tinker, which perhaps gives a little license to put additions on I feel, provided the spirit of the original is kept 😉
Anyway, as everyone just presumes it is a Morgan when they see it, the more BSA labels I can get on it the better
