This car took part in the HSCC Atlantic Computers Historic GT Championship race at the HSCC's Spring Historic Race Meeting at Oulton Park in May 1987.
It's a 1967 Lola-Aston Martin T70, one of two cars built to compete in the 1967 Le Mans 24 Hour race, although both cars retired very early in that race. The car was entered in the Oulton Park race by Peter Millward and driven by Mike Wilde.
Here's Mike Wilde at Old Hall Corner during the morning practice session, followed by the 1969 McLaren M8C of Ted Williams.
On 6 October 2015 I showed a photograph of a Lola-Aston Martin T70 at the 1996 Coys International Historic Festival meeting at Silverstone, but I don't know if it's the same car as this one, or the sister car.
