By the way, I have more to add on my Model 5, if, as Jonesy believes, it was an original Series 1...(Predicta axle housing and base extensions), it also has the 2 hole carby top with one hole blocked off with a silver fitting with the letter 'V' stamped into it....and on pulling the handles apart, it had the remains of a plastic badge consistent with the original Special badge....In fact, I still have the broken piece. You can see it in this pic, the day Joe Carroll got it at the swap meet....
