The Coys International Historic Festival meeting at Silverstone in July 2000 celebrated 50 years of the Formula 1 World Championship, which started with the British Grand Prix at Silverstone in 1950. There was a display of a representative selection of Formula 1 cars from those 50 years and here's one which saw action in 1979.
It's the Ferrari 312 T4 with which Jody Scheckter won the World Championship in 1979. Scheckter won three races, the Grands Prix of Belgium, Monaco and Italy, and his team mate Gilles Villeneuve won the South African, United States and United States West races, finishing in second place in the Drivers' Championship. Ferrari, naturally, won the Constructors' Championship.
