Like 2021 Rankings winner Jackson, Harrison is taking victories in Historic Formula Ford 1600 plus another category, in his case Historic Formula 3. Two successes were scored at Brands in his HF3 Chevron B15, plus two in his HFF1600 Merlyn Mk20, both machines prepped by the Silverstone-based SpeedSport squad.
Harrison is not the only driver to join Rankings top dog Lucky Khera on double figures this week. Scottish Legends exponent Stewart Black shot into contention last month with six victories at one event, and last weekend he added another two at Knockhill, his tally kept down on this occasion by triple winner Ryan McLeish.
