no real photos of the mythical Spragthrope kennel of models exists just one off extremes posted in jest as a rub on the make shift complex constructions of antique to vintage cycles I think Norton was the main inspiration for, like the race bike that rear suspension pumped fuel so crew would pump suspension before a race and other teams did the same but not knowing why, or the infamous sprag of MK3s that even best mechanics can not get to last long. I am sure the German cycle with engine in the front wheel was also inspiring.
