For Legion's excellent Cooper T61P Maserati.
Before the car was painted in its dark green/reddish orange livery for 1964's British circuit stints, the car ran it's debut in unpainted, bare aluminum. The car had only just been finished after all, and no time was spent on the "unnecessary" details like paint.
The first race at Silverstone went quite well for Salvadori & the "Cooperati", finishing 2nd overall and snatching a class win. Two weeks later this would be followed by an outright win at Goodwood.
Special thanks to Rodger for the ext_config!
