Brabham BT30  (Jack Brabham): New to John Coombs Racing and entered for Jackie Stewart and Jack Brabham in F2 in 1970. Fitted with a Cosworth FVC for Stewart to win the 1970 JAF GP. To Mike Goth September 1970 for three late-season F2 races. To Silvio Moser (Lugano, Switzerland) for F2 in 1971 up to Rouen in late June, after which Moser had a BT36. The next stages of this car's life are unknown but a 1996 Coys auction catalogue said that it had been used in hillclimbs until bought by the then current owner in 1976. The car was sold after the auction to Jay Galpin and then on to Bob Baker.
Autosport (9 Apr 1970 pp12-14) doesn't give chassis numbers but does mention that Regga was in his Thruxton car and Cevert had "a completely new and unsorted" one. Miles' Lotus 69 was equally untested and Jabouille appeared with a third Pygmée.
