Hi anyone interested, 
I have a Cheetah frame, engine, and I think original tank which I will initially put together with some Fantic 240 wheels I have. More genuine wheels may be added later if they turn up at a price I can afford! I remember Arthur Dovey and Paul Dunkley were supported riders in the Southern Centre and worked closely with Bob Gollner. I haven't got details of their whereabouts.  
Also very interesting is that they tried out a cable operated front disc brake on some of the bikes - prophetic stuff back in '67/'68!! 
I'm looking forward to any info that is unearthed! 
Nigel
