Hello again, I have found out more about my father-in-law, Harley Dillon. He raced speedcars at Rowley Park and was killed in the Encourage Handicap Race on 25 Feb 1966. He apparently raced solos about 10 years prior to that. He also was the social secretary of the Racing Drivers association at some point. The race he was killed in also had John Nash, Nick Jackemis and Jim Silvy in it (I think he landed upside down on John Nash who wasn't hurt). I'm hoping this helps jog peoples memory. We would like to hear from anyone that knew him, remembers him or has photos or stories from that time period.
