This car took part in the Chopard Grand Prix Cars Race at the Coys International Historic Festival meeting at Silverstone in July 1993.
It's a 1958 Vanwall, chassis VW10, owned at the time by Vijay Mallya - who later became leader of the consortium which ran the Force India F1 team.
The programme of the event said this about the Vanwall:
In 1957 and 1958 British Racing Green finally became the dominant colour in grand prix racing, thanks to the efforts of the Acton-based Vanwall team. After winning three of the last four world championship grands prix of 1957, the Colin Chapman designs were successful in six 1958 races, giving Tony Vandervell, the car's sponsor, the world F1 constructors' championship.
Only one of the original team cars was kept, and it is here at the Coys International Historic Festival. Acquired recently by Vijay Mallya, the Vanwall is entered at Silverstone with the incomparably experienced John Harper as driver, and he will be striving to ensure that its reputation among Formula 1 cars of the era is preserved.
For many racing enthusiasts at Silverstone today, the sight of the Vanwall being raced in anger once again will alone be worth the price of admission, and will bring memories flooding back to those who lived through the years when Britain was struggling to make her mark in the international grand prix arena.
There was a special display of cars, including the Vanwall, to mark the meeting's theme of British Racing Green.
I was fortunate enough to be at Aintree in 1957 when Stirling Moss and Tony Brooks shared the winning drive in a Vanwall when it became the first British car to win a World Championship Grand Prix.
This is the view other drivers most frequently got of the Vanwall in the 1958 season.
