This piece about one of the last sprint bikes campaigned by George Brown comes from the pages of a 1966 edition of Motor Cycle magazine. Before coming of age (55) to hold an FIM licence, George decided to build Super Nero and Extra Nero to run 200 mph using a Vincent engine and frame. Did he do it? Well perhaps someone on here will be able to confirm that. And, I'm almost certain that these two bikes George created are currently on display at the National Motor Cycle Museum, Solihull!
