Patsy Burt's McLaren was blue and white. (Pic published earlier).
Car 158 I thought was 1970 Prescott but double checking through, it seems as though it must have been May 1971, in which case it was well known hillclimber Roy Lane's McLaren M10B - but with 5,500cc according to the programme, not the usual 5,000cc.
Johnty Williamson's Cooper Chrysler was packing a 7,200cc motor!
Mike MacDowell (who I met in NZ a few years ago at a McLaren Trust do in Newmarket) was driving John Cussin's Palliser Repco 3000cc but I don't have a pic of that. If it was yesterday, I'd probably have a couple of pics of every single car running!
Loton Park August 1973 and Roy Lane again, but McLaren M14D, 5,700cc
