Alan Shepherd retired on the second lap of the 1964 Junior; I think he was laying second at the time.
Jim Redman rode a 125 'Barcone' Ducati before he took up with Honda. this machine now resides in the US of A, and the current owner would like to find out more information about it. I gather that Mike Hailwood rode (and fell off it at my feet) in the 1960 Ultra Lightweight at Glen Helen.
