A Surtees TS9 ahead of a McLaren M19 and a March 721: British cars and drivers dominated the 1st free practice session for Race E, meant for F1s of the beginning of the 70s.

And Michael Lyons was faster than Stuart Hall and David Shaw, his fastest lap in 1:38.711. Not bad for a 50-year-old car. A Ferrari and a Brabham completed the Top 5.
