Thanks for the replies, I am mainly interested in the engine design, (but any pics are welcome).
I already have some engine pics (not very distinct) and a short descriptive story by Wardill himself and it now seems that it was published in one of the 1974 editions of Motorcycle Magazine.
However, it has re kindled my interest again and I was wondering if it is possible to get a relevant copy of "Motorcycle" magazine from the archives, wherever they are.
Maybe if someone has a collection of these mags and could ferret out this particular article for me I could reimburse him in some way if necessary. ( from memory the original caption read " That's what happened to the Wardill".
If any of you are interested i might try and scan the article and pics but sometimes these type of things don't travel very well electronically and the fact that they are already indistinct doesn't help!
PS I think it was October edition 1974 of "Motor Cycle"
