What excellent archive films! Thanks. Re the 1963 season in post #2591 and the Mallory Park meeting, I was there and it brought back memories of a great day. I thought that the 3 hour saloon race for under 850cc cars had the potential to be a yawn, but of course it was anything but. It was an absolute hoot as can be seen in the film. BMW 750's are rare beasts today but proved their worth on the track back then. I was told that they had motorcycle heads on which had bigger valves.
Also seen fleetingly in the footage from that meeting are Chris Kerrison's special bodied 250GTO and the UDT Laystall 250GTO (presumably Innes Ireland). In the nutty 1300cc saloon race, Christabel Carlisle get plenty of footage, but note the white 105E Anglia number 62. That was (IIRC) driven by Anita Taylor, and very competently too. As you can imagine, she made a lasting impression on me as a 15 year old boy.
Here is a photo I took at the meeting of Graham Hill signing autographs whilst I waited my turn. Happy days.
