Brabham BT43

1974

Owing to a combination of factors (not the least of which was the closing down of the MRD side of the Brabham business) the BT43 did not make its debut until June 30, 1974 at round 10 of the 1974 Rothmans F5000 Championship at Monza driven by Martin Birrane. Qualifying 15th in a field of 19 Birrane failed to finish retiring the car on lap 16. Birrane drove the car twice more: round 11 at Mallory Park on July 14, 1974 where he did not qualify; and round 13 at Thruxton on August 18, 1974 qualifying 15th in a field of 19 but again failed to finish retiring the car. This was to be Birrane's last appearance in the car as at the next round (round 14) at Brands Hatch on August 26, 1974 American Brett Lunger drove the car. Qualifying an impressive 7th out of a field of 21 on the Brands Hatch short circuit Lunger unfortunately had an accident on lap 28 of the scheduled 60 laps and retired the car. The BT43 did not make a further appearance in 1974 until the last round (round 18) of the 1974 Championship again at Brands Hatch but this time on the Grand Prix circuit with Chris Craft in the cockpit. Qualifying 13th out of a field of 25 Craft finally registered a result for the BT43 by finishing 7th completing 34 laps one lap down on the final round winner Australian Vern Schuppan driving a Chevron B24/28 for Team VDS. Double points for this final round helped to boost Craft's personal points tally in the series to 67 to finish equal ninth with compatriot Brian Redman.

1975

Round 1 of the 1975 Rothmans F5000 Championship at Brands Hatch on March 15, 1975 on the Grand Prix circuit saw Brett Lunger return to driving the BT43. Qualifying 15th in a field of 21 Lunger unfortunately had an accident on the warm-up lap and failed to start the race. The car did not appear again until round 4 at Silverstone on April 12, 1975 again in the hands of Lunger but this time sporting a new nose taken from a BT42. (This is possibly one source of the BT43 being erroneously described in some publications as a modified Formula One car rather than a purpose built and unique F5000). Qualifying 10th out of a field of 21, Lunger again failed to finish retiring on lap 12 of the scheduled 25 laps. The car made no further appearances in the 1975 Rothmans F5000 Championship.

Following its purchase by Chuck Jones in the USA the BT43's next appearance in 1975 was to be at the California Grand Prix which was round 9 of the 1975 US F5000 Championship at Riverside on October 26, 1975. With Jones as the entrant the BT43 was to be driven by Dick Parsons. However the car failed to arrive having been crashed by Parsons in testing. Records of what happened to the car after this and who and where it was repaired are non-existent.

1976

In late 1976 Australian racing driver Kevin Bartlett became aware of the car whilst in the USA and tested it at Willow Springs. Impressed by it he began negotiations to acquire it with the intention of using it in the 1977 Rothmans International Series in Australia. However an agreement was unable to be reached in time for the 1977 series.

1977

The repaired car's next appearance (sporting a new nose) was not in a race but in a motion picture as it was used in the filming of "The Betsy" during 1977. The car was the open wheel race car of the racing driver character named Angelo Perino played by a youthful Tommy Lee Jones.

1978

Following the conclusion of negotiations between Jones and Bartlett the BT43 arrived in Australia in early January 1978 to participate in the 1978 Rothmans International Series. In a series dominated by Australian driver Warwick Brown driving a Team VDS Lola T332C with four wins from four starts; Bartlett in the BT43 could not manage a points finish with sequential results of Retired, 8th, 15th, and Retired.

The first round of the 1978 Australian Drivers' Championship at Oran Park on July 30, 1978 proved to be more successful for Bartlett with a second place finish behind the McLaren M23-Leyland of John McCormack. This proved to be the highest placing achieved by the BT43 in its career. A distant 5th place finish in the 1978 Australian Grand Prix at Sandown on September 10, 1978 which formed the second round of the 1978 Australian Drivers' Championship kept Bartlett in with a chance of taking the title. The third and final round of the series was run over two heats at Calder on October 15, 1978. However no points at the final round meant that Bartlett finished the series in a distant third place on 8 points behind the winner Graham McRae in his McRae GM3 on 20 points and second placed John McCormack in his McLaren M23-Leyland on 12 points.

1979

For the 1979 Rothmans International Series the BT43 was handed over to Colin Bond to drive with Bartlett reverting back to his Lola T400. Bond had two points finishes with a 9th at the second round at Adelaide International Raceway on February 11, 1979 and a 4th at the fourth and final round at Oran Park on February 25, 1979. With additional points being awarded for the final round compared with the first three rounds, Bond's points tally was boosted to 14 points which meant he finished the series in a relatively flattering sixth place. Bartlett by comparison finished a lowly fifteenth on 7 points.

With the first round of the 1979 Australian Drivers' Championship also being the 1979 Australian Grand Prix held at Wanneroo Park on March 11, 1979 - only a fortnight after the final round of the 1979 Rothmans International Series - neither Bartlett or Bond made the trip across the continent to contest the Grand Prix.

When the BT43 made its next appearance at the second round of the 1979 Australian Drivers' Championship at Oran Park on July 29, 1979 two factors were evident. The first was dramatic modifications to the car primarily to cure the chronic lack of front end downforce exhibited since initial testing and in Bartlett's words its "unhealthy transition to spectacular oversteer"; while the second was the sponsorship of Bartlett's racing activities by Kerry Packer's Nine Television Network. Modifications included: a new nose (similar to that of the Lola T400); removal of the nose mounted radiators and replacement with two new radiators mounted on the end of each upper side of the pyramidic monocque; and the change in livery. All of these changes were for nothing however as owing to an engine issue during practice the car failed to start the race. The third and final round of the 1979 Australian Drivers' Championship at Sandown Park on September 9, 1979 proved to be the BT43's final race. One further modification to the car was the addition of a new airbox which again was similar to that fitted to a Lola. Bartlett had taken a deposit on the car and raced it for its new owner. Bartlett was in second place early in the race - ahead of eventual second place getter and series winner Johnnie Walker driving a Lola T332 - and entering the bridge turn Bartlett had the centre of the right rear Dymag wheel collapse sending the BT43 into the catch fences breaking Bartlett's leg and arm and significantly damaging the BT43.

Mystery of whereabouts and confirmation of demise

Whilst Bartlett was convalescing, Customs demanded that the duty be paid on the car or that it be exported. The prospective owner who had paid the deposit then sent the car "freight on" to a friend in the UK who refused to pay the bill. At this point in time (late 1979) all trace of the car disappeared and it was assumed that either the UK Customs or the freight forwarder had disposed of the car at the docks.

Questions over the BT43's whereabouts were raised in a thread on The Nostalgia Forum on the Autosport website on October 12, 2004 and it was not until September 17, 2013 that the mystery of its demise was confirmed by a post in the same thread.
