Hi Robert, my understanding was that Bobby Brown's Camaro became the SCA Freight Camaro that was raced in the UK and Europe by Frank Gardner.
In late 1972, Gardner shipped the Camaro to New Zealand where he contested a couple of events at Bay Park and Pukekohe, then continued on to Australia in early 1973 where it was raced at Warwick Farm and Sandown.
I believe Bob Jane purchased the Camaro to on-sell, which he did. It was sold to John Pollard and raced for many years as a Sports Sedan. It eventually found its way to Rowan Harman, who planned to restore it but instead sold it to a buyer in the UK, where it returned and has since been restored back to its 1971 SCA Freight guise, and competes in selected historic racing events.
Below is the car at the Goodwood Festival Of Speed.
I say all that, but recently Chris Bowden in Australia, whose family owns a large collection of important historic race cars, told me Frank Gardner said the SCA Freight car was in fact not the Bobby Brown car. Maybe someone here can shed some light on this?
