Come 1969 though, it was all change. Brabham dumped Repcos for Cosworth DFVs, and with the renamed BT46A, the Aussie’s eponymous team was back in business. Rindt made his ultimately fateful move to Lotus, and so was replaced by Ickx.
The Belgian would switch between Chassis 3 and 4 throughout the season, but it was this one with which he would take victory at Canada that year and ultimately end the season as runner-up to Jackie Stewart. Ickx would also claim Oulton Park’s non-championship Gold Cup race that season in the same car.
After that the No3 went on to have a colourful post-Brabham history. American Gus Hutchinson would purchase the car and compete in the US-based SCCA championship, winning two races as well as qualifying it for his home race at Watkins Glen in 1970.
This car, which was eventually sold at auction three years ago for £800,000 ($1.1m), is currently in storage in Miami, but is more than ready to compete in historic events should its owner wish to, says Hanson.
