Jim Clark stops his Lotus 39 to collect a celebratory beer after winning the 13 February 1966 ‘Warwick Farm 100’ Tasman round…
Clark won the Tasman Series in 1965, 1967 and 1968. His 1966 mount, whilst a good car, the 2.5 litre Coventry Climax four-cylinder engine was outgunned by the ex-F1 BRM P261, the capacity of which had been stretched from 1.5 to 1.9 litres with Jackie Stewart winning the championship taking four victories from eight rounds.
I wrote a feature article about this one-of-a-kind Lotus 39 a while back; https://primotipo.com/2016/02/12/jim-clark-and-leo-geoghegans-lotus-39/

Jim’s only 1966 Tasman win was in Sydney- Barry Hickson took this photograph whilst a flag marshall at Homestead Corner recalled that Dick MacArthur Onslow, the Homestead Sector Marshall promised Jim a ‘cold one’ if he won, here in the opening photo, the great Scot has pulled up to collect the promised cool beverage from Dick!

Clark excelled at the technical, depending, outer Sydney track, he started from pole and won from Graham Hill, BRM P261 and Frank Gardner in Alec Mildren’s Brabham BT11A Climax with JYS fourth in the other P261.
In fact the ‘Farm was a very happy hunting ground for Jim, he raced there from 1965 to 1968 winning on three of his four visits aboard works Lotus machines- 1965 32B Climax FPF, 1966 39 FPF, and in 1968 aboard a 49 Ford DFW, the 2.5 litre variant of the 3 litre F1 Ford Cosworth DFV. In 1967 he fell short of the mark but not by much taking second to Jackie Stewart’s BRM P261, that Tasman Series the BRM V8’s were stretched to 2.1 litres in capacity. Jim’s 1967 car was an F1 Lotus 33 Coventry Climax FWMV 2 litre V8.

Victory for Clark at WF in 1966 aboard the Lotus 39- a car which would become iconic in Australia thereafter in Leo Geoghegan’s hands in both Coventry Climax and Repco V8 engined forms. And still resident in Oz (unattributed)

Tailpiece: Clark on the way to his 1965 Warwick Farm 100 win, this time in his Lotus 32B Climax, Homestead Corner…
And the same 32B chassis in the WF paddock beside Jack Brabham’s Brabham BT11A Climax, with Roy Billington toiling on Jack’s car. Is that Ray Parsons behind the 32B? Who is the Repco clad bloke looking at Jim’s car who attended to Jack every year whilst he was in Oz?
Finito…
