Alison, there was a ship load of makes being used, they ranged from a complete bike from Jawa to a bittsa of a number of manufacturers, Inc - Engines & Frames.
There are a couple of sad stories in some of those last photos Freaky.
Englands whiz kid Kenny Carter in the Halifax team shots, commited suicide as did our own Billy Sanders.
Neither could cope with the national & personal pressure they put on themselves to win a World title, both were leading riders roughly the same time.
In Billy's case, his wife running off with one of his best mates didn't help, sadly his son also made the same
choice.
