Series D, which collected the cars from the 1961-1966 Grand Prix (Formula 1.5 litres), had lived on the clear dominium of Andy Middlehurst with Lotus 25, in one of his rare appearance. The British driver has dominated since the first practice in the style of Clark (even if there the Scotsman hasn’t always be so lucky), crossing the finishing line with 9 seconds’ lead over the Cooper driven by Sidney Hoole and the Lotus 24 with Paul Dryson, also authors of a lonely race. there was much more excitement in the fight for the fourth place, with an interesting little train made by the Brabham BT11 with Walzer, the Cooper T71 with Baillie, the Lotus 21 with Collins and the 24 one with Wanty.
The first in the lead of the group was Baillie, confirming his fourth place scored in the qualifying session, but Walzer had immediately managed to threaten the driver’s position: he made an attempt on lap 4 before the Rascasse. It seemed successful but then he found himself behind. On lap five he tried again on Sainte devote and then again up the hill toward Massenet. At last he hit definitively the mark one lap afterwards. Behind them, Wanty tailed Collins as a shadow, but the rival didn’t allow much.
A small mistake for Mister John of B who crashed the nose of his Lola against the guardrails of Sun Casino (former known as Loews Hairpin, or Station Hairpin before that) A little back and forth, style manoeuvres of mooring, and the driver took the track again. Anyway a classic error here in Monte-Carlo.
