You don't happen to have any shots of car 57 in race 7 do you? It's a black Lola T492 so, apart from the colour and minor details, it looks exactly like car number 30 in your original post. If by any chance you do I would be chuffed if you could send me a copy as your shots are indeed excellent.
Thanks,
Si.
