Let's not forget there was more than one bike, Mike's and Ralph Bryans, the earlier ones from Jim Redman and of course the 250 and 297 versions. Think no one can tell after all these years which is what and which did actually survive. Know that back in 1980 when Mike rode a 250 during a break at the TT of Assen, it was a genuine bike, heard Mike telling that to a journalist while I was lying on my knees behind the bike. Must caused my hearing problem btw. when it was started.
