For the season, Martino Finotto bought two Brabham BT42s, and leased both cars to the Swiss Jürg Dubler, a retired racing driver. Jurg Dubler entered both cars for the 1974 Spanish Grand Prix sponsored by Silvio Moser's backer Bretscher, one for Silvio Moser and the other for the Swede Reine Wisell, but one week before that race Moser was seriously injured during a sportscar race at Monza and died four weeks later. The team had only one full-time mechanic, New Zealander John R.Anderson, and an engine builder, Englishman R.John Leslie, and used Lino Branca's workshop in Buscate and Novamotor's engine dyno. The team had no spare parts for the cars so often had to rob parts from one car to keep the other running. Dubler bought one new Cosworth DFV but this destroyed itself during testing before the French GP. The other two engines supplied by Brabham with the cars were old small port engines that were less powerful and unreliable.
