I found this remarkable film quite by chance.....please take a look... Jack Findlay - Wikipedia, the free encyclopedia Jack Findlay - Telegraph
The film is chaotically edited, muddled, badly sub-titled, and obsessively morbid. It also has a lot of interesting shots - if you are interested in what racing was like in about 1971. Whenever riders tried to get together to boycott excessively dangerous tracks, Jack Findlay was the blackleg.
