The fan you are talking about is the professor Harry Lundberger. He passed away in 2005, I have some photos of Harry which I may post if permitted, Harry was a RR champion in Sweden, I once gave him a cup of tea at Billown pre TT races it was pouring down I invited him into my race transporter to warm up and dry out although under the waxed coat that he always wore he was probably bone dry, I am sure he was a cult figure for the purple helmets, he carried everything in that pizza type box on the back of his step through including tools and a full size brass Dunlop footpump, many took the micky at the way and slow speed he rode, if only they knew.
