I took this photo of Pete Allan's twin Triumph at Santa Pod in 1968 when I was competing in the 350cc class.
Hi Jon, the dble kwak at the top of the with a ? was built by Tom Quin then sold to Daytona M/C and ridden by Bob Webster, also the double imp bike was built by Barry Townsend not Allan Thompson, it was only run once & was deemed useless by Barry as 3 brng cranks were not a good Idea and the bike was scrapped, it did appear at the 1980? crystal palace drag show alongside my Líl Hooker funnybike.
Thanks for the mems and keep up the good work. Cheers Rod
