I'm writing up my Dad's memoirs for eventual publication. As an aside to the main topic (a life in the RAF), he mentions that, sometime around 1946, he had made for him a lightweight bicycle by Percy Ellis of Fulham, proprietor of Champion Cycles. It was a Reynolds 531 frame, fixed, in light green, and was used for serious touring all over UK. I'd love to flesh this part of his story out, and if I could get any pictures of a similar bike, that would be great! Does anyone have any information?
