The Wills you mention, Ian, was from W.D. & H.O. Wills of cigarette fame. Johnnie Hoskins was a brilliant entrepreneur. He is survived by two sons, Ian who lives in NZ (where Johnnie was actually born) and Lionel, lives in England.
What lovely memories you have unearthed. Lionel has a great pic of his dad receiving an MBE (I think it's called from the Queen). Can you believe that in those early days, royalty used to visit the speedway. There are photos of Johnnie taken with one of the Princesses who visited on a regular basis. Can't remember her name. But the crowds were unbelievable.
Bluey Wilkinson was an Australian favourite. Enjoy those finds.
