I'm not really on the pace with this... but isn't it 'Denis' Welch?
But I feel sure there was possibly a car that went to South Africa that could have gone on to England. The Hengkie Iriawan car (fitted with an FVA originally) is, IIRC, 'missing'... this all being somewhat distant memory from when I wrote the story about the model for the
Fast That's Past series.
The 'expert' in the field is Paul Hamilton, of course. He keeps (or is it 'kept'?) a register of 600s and still owns the original car himself.
When he went to England shortly after the death of his wife, his plan was to find and buy the Iriawan car (with its history making it the only car of its era that could compete using an FVA engine) if he could find it (so it must be in England, no?) and to buy a Ferrari Dino 246 if he couldn't find it.
I don't know if he still has the Dino, but I feel sure he probably has.
Anyway, FWIW, here's the story on the model:
IN AN ERA of smaller and sleeker monocoques, the tube-framed Elfin 600 not only refreshed the fields of Australian racing, but sold well and lingered at the front line into the seventies.
GARRIE COOPER had persevered with the Elfin Mono, bringing out a Mk 2 to overcome the deficiencies of the Mk 1, but in April, 1968, he surprised everyone by reverting to a space-frame for his new car, the Elfin 600.
This logical step should be seen in concert with what had happened in front line racing in Australia since the introduction of the Mono.
Brabhams were the leading cars, it has to be said. And they were tube-framed, and the frames were much the same from European F3 through to Tasman cars, and not that different for F1, either. Frank
Gardner had shown the way by bringing the F2-based Climax-powered car out for the 1967 Tasman series.
Significant manufacturing savings were to be had with such a wide range of applications of what was essentially the same chassis, and there were other benefits.
Like the ease of varying tankage, plumbing, changing suspension geometry (tyre sizes were changing at the time), and simply changing engines.
Unafraid of appearing to go backwards (his Monos were doing some winning, after all, particularly at Calder), Cooper jigged up the first 600 and put it on the track for the first time at Calder, home of 1.5 racing by virtue of the Lucas-Davison series and its successors.
On March 23, 1968 the car took third place on its debut. It was promptly fitted with a 1600 twin cam engine and sent to Kuala Lumpur, where it broke its gearbox while leading.
This was to set in train another significant change, but not until after the car won the Singapore GP, a major win for the marque Elfin. It was then sold to Hengkie Iriawan, who was to do some more winning with it, and was to become one of a number of repeat customers for the 600 model.
The change created by the gearbox failure was Garrie’s determination that all ‘works’ F2/1.5 cars would be fitted with a Hewland FT200 in lieu of the Mk 5 that had been fitted in the past. That first car soon had the box changed, and most customers were encouraged to spend the extra money.
So the Elfin 600 was listed as a production model with A, B and C variants. It had a space frame chassis with the water running forward to the radiator in the top left main tube, returning in the bottom right tube, while the top right tube performed the function of ventilating the crankcase to the oil tank in the 600B.
Suspension at the rear was very similar to the last of the monos, using the same uprights until they ran out of stock and were replaced by one with an extra mounting for the AR brake caliper.
Conventional for the time, it had a reversed bottom wishbone, and leading arms, with a single link at the top and a conventional sway bar. Armstrong dampers mounted coil springs.
At the front it followed the normal pattern as well, conventional layout being very much a trademark of this Elfin. A wide-based bottom wishbone and an upper link with trailing arm attached the ball-jointed Triumph Herald uprights to the chassis, with the ubiquitous Armstrong and coil controlling movement, again aided by a sway bar with sliding adjustment.
The Herald uprights were fitted with an alloy caliper mount for the alloy brake calipers, and also had a fabricated brace that went from the caliper bolts to the back of the stub axle, itself an Elfin component, the other end of which carried the cast alloy Elfin hubs and the 10.5” discs.
At the rear of the chassis the top crossmember was removable to facilitate engine and gearbox changing, but after the tenth chassis, only those belonging to Cooper himself were to enjoy this feature.
So we look at the cataloguing of the the A, B and C models. The 600A was intended for 1100cc cars, at that time called ANF2 (1.5s were called ANF1.5, 2.5s ANF1), and was a base model (with smaller wheels iron calipers, non-adjustable dampers) that never saw the light of day.
The 600B was the model that became very popular, running at the head of the field in ANF1.5 and the new 1.6-litre category when this came in.
The 600C listing showed where Cooper intended going with the model, for it was listed to take Repco V8 and Climax engines. It would feature larger fuel tanks and top-of-the-range fittings in all areas, wheel sizes up to 15 x 12.5 being quoted.
There were to be, naturally enough, running changes. The eleventh car in line, coincidentally a
Formula Ford, carried an all-new front body which gave more of a straight line from the top of the radiator inlet to the windscreen, which was minimalised with this body.
Additionally, there were fiberglass side panels that came in tighter around the pedals and gave more vent room for the radiator. Prior to this the tanks were the side panels, but the smaller tankage requirement for FF meant side panels had to be made, so they went on all subsequent cars.
The numbering system changed for FFs, too. Previously the numbering had been the year followed by a two-digit number for the sequence in the series. FFs had a three-digit number after the year.
By the time the first 600C was built, Garrie introduced fabricated steel front uprights. This car was fitted with a Repco V8, but others had a Climax 2.5 (John McCormack) and a Cosworth FVA (this was the replacement Hengkie Iriawan bought).
With the Repco V8, they were the only Australian designed and built car to mount an all-Australian challenge in 2.5 form.
The 600D was a model designation showing that there were changes, and these centred around a new layout for the rear of the chassis on the second Repco-powered version Garrie raced. It was later to revert to a more normal frame as he changed it back to a twin-cam, and he ran this car with a full width “Tyrrell” nose, copied also on the Jack Bono 600B.
The last designation in the line, apart from the FF, was the 600E. Mostly cars carrying this specification were upgraded 600Bs, but at least one was built fresh for Bill Patterson Motors when they ran the car for Henk Woelders.
There was new geometry at the front and cast magnesium uprights to differentiate these cars from the others.
What really makes the 600 stand out is its commercial success. No fewer than 44 cars were built, possibly 45, which makes it the largest volume of one model race car ever built in Australia.
They were successful, too. They won titles in 1.5 form, Garrie sharing the 1.5 title of their first year with Max Stewart, then in 1.6-litre form the championships of 1971 and 1972 went to Henk Woelders and Larry Perkins respectively.
In Gold Star competition there were some heady displays, even though the Repco V8 was no longer the preferred gear by the time these cars were so fitted. Cooper won a round at Mallala, which seemed to really suit them, while McCormack had a pole there in 1970 and took out the outright lap record in the race. What’s more, the Elfin 600C of McCormack is in the books as the fastest ever Repco V8-powered car around the Warwick Farm circuit, lapping in 1:27.6.
In Formula Ford the cars endured a long time. The first car went to Bib Stillwell, and his two-car team wiped the board for the first two years of the series, while wins kept on coming for years afterwards.
Of those built, it’s interesting that only one is known to have been destroyed. That was the Glynn Scott car, which went under the Armco at Lakeside very early in its life as Glynn was really enjoying the Waggott power and a fine chassis. The Iriawan 600c, however, is listed as ‘present whereabouts unknown.’
So it was a car that really achieved its purpose. Cooper’s first-class spares service and other backup helped owners all over the country to win races week after week.
Among those winners we would have to list Bruce Allison, Gary Campbell (another to go Waggott at one stage), Clive Millis, John Walker, Malcolm Ramsay, Jack Bono, Maurie Quincey, Ivan Tighe, Vern Hamilton, Tony Maw and Don Eubergang. In F3 there was Bob Minogue who became almost unbeatable in one.
It was exported, too, in Formula Ford form as well as the more potent models. One overseas buyer was Teddy Yip, who bought one principally for others to drive for him, one such driver being Allan Moffat. That car now resides in a museum in Macao.
So the path Cooper followed was the right one. A chassis that would allow flexibility in fitment of engines – even though the Repco V8s demanded some changes in the C version, but not as radical as was done with the 600D – and could be developed for a number of categories concurrently.
That it achieved successes in every category it entered shows the soundness of the design. For it to have done so well right off the jig, filling third at Calder and taking that Singapore GP within weeks underscores that thought.
For its continued success, all Cooper needed to do was keep on applying himself to the task. He obviously did this well.
Of course, they abound today in Group O and other Historic categories, still holding their own against imported cars.
