Queensland single-seater pilot Henk Woelders adjusts his helmet, probably Lakeside, 1967…
I was musing online with some ‘Nostalgia Forum’ buddies the other day about the effectiveness of the Castrol liveried brothers Geoghegan racers of the late sixties and early seventies. The commercial message was delivered well because of the elegant simplicity involved.

Henk Woelders’ Elfin 600 liveries are other fine examples of ‘getting it right’.
He raced two of the spaceframe cars, both ANF2 machines, the second to the 1971 Australian Formula 2 Championship, taking four of the six rounds in his Bill Patterson Motors sponsored car. This chassis was a 600E, Garrie’s you beaut late F2 machine which had magnesium front uprights and revised suspension geometry front and rear.
Henk’s cars had Patto’s simple light blue stripe on a white background, Patterson’s own racing colours from his Cooper Gold Star winning days a decade before.
Sometimes photographs appear from the most unlikely of places, the inspiration for this article was two shots taken by the Australian ‘Department of Immigration, Multicultural and Indigenous Affairs’- catchy innit?
It seems the DIMIA were running some articles at the time about migrant success stories in Australia, as you may have gathered from the Woelders name he hails from the Netherlands- one of millions who came to The Great Brown Land post-war in a ‘populate or perish’ policy by our national governments. It would be intriguing to know where these photos were first published.
The shots are dated 1967 and refer to Henk with his Lotus Super Seven- which the first opening photo may be but the second most certainly is not. Lotus 20 FJ maybe?- did they have rear drum brakes?, intrigued to know what the car is if one of know what he was racing at the time.

Woelders in his first 600, a 600B chassis ‘6806’ at Calder before the hi-wing ban imposed over the ’69 May Monaco GP weekend. A moveable aerodynamic device too- clever setup has the wing feathered on the straights as here- with incidence created when required- interested to know who engineered this clever setup (B Mills)
What limited information I have indicates Henk was employed by Patterson during the Elfin 600 period, so at some point he moved from Queensland to Melbourne, presumably working at Patterson’s Holden empire based in Ringwood, an outer-eastern Melbourne suburb.
Harry Firth rated him as a driver, Henk and Peter Macrow were the ‘open-wheeler’ duo in the Holden Dealer Team’s first successful, three car 1969 Bathurst 500 assault- Colin Bond and Tony Roberts won, Des West and Peter Brock were with Woelders/Macrow sixth.
Henk’s career seems to have ended after his F2 win but he was reunited with his championship winning 600E ‘7024’ many years later and still retains it, and a very nice car it is too.

Henk and Malcolm Ramsay- in 600E and 600C ‘6908’ get set for the August 1971 Glynn Scott Memorial Trophy Gold Star round at Surfers Paradise. The F2 Championship race was run concurrently with the F5000 cars- Henk won the F2 section finishing 6th and Frank Matich was first outright in his McLaren M10C Repco. Ramsay DNF with a broken throttle cable- both these cars were powered by Merv Waggott built Lotus-Ford twin-cams (S Johnson)

Tailpiece: Woelders, Elfin 600B, Lakeside 1968…
John Stanley’s photo above is of Henk’s first 600 coming out of Lakeside’s Eastern Loop in 1968, he raced this car from 1968 to 1970 before replacing it with the later model.
Elfin 600’s won goodness knows how many F2 races in the hands of drivers like Garrie Cooper, John Walker, Tony Stewart, Ivan Tighe, Maurie Quincey and Australian Championships for Cooper, Woelders and Larry Perkins in Gary Campbell’s 600B/E in 1968 (ANF 1.5 C’ship shared with Max Stewart) 1971 and 1972 respectively.
Elfin’s Australian F2 dominance is amply demonstrated by the 1971 championship table- the first eleven placegetters raced Elfins- Woelders, Tony Stewart, Jack Bono, John Walker, Ivan Tighe, Garrie Cooper, Vern Hamilton, John Ampt, Ken Hastings, Ross Ambrose, Clive Millis and Don Uebergang!
Of those, all raced 600’s with the exception of Ampt who was aboard a Mono- the monocoque Birranas finally rained on the Elfin F2 parade from 1973…
Finito…
