I saw this car race at Silverstone in 1981 in the hands of Derek Bell as support to the GP and it was one of the most memorable races I ever saw as he started from the back of a 30 odd car race and won! Epic battle with a Albert Orbist in a Ferrari 312 and I had lost track of it and couldn't find it in any of my references but this bloke mentions that actual race in video 2.
