The BRM P139 was a Formula One racing car designed by Alec Osborn, [1] based on the original P126/133/138 design by Len Terry, which raced during the 1969 and 1970 seasons. It was powered by a 3.0-litre V12 engine. The car was uncompetitive, which resulted in team boss Tony Rudd being asked to resign, with his position being taken over by Tony Southgate, Tim Parnell and Aubrey Woods. [4] After the team did not attend the French Grand Prix, a redesigned P139 appeared at the British Grand Prix, with a roomier, more bulbous cockpit and additional strengthening, giving the P139 a cylindrical appearance. [4] The revised car was barely an improvement on the original P139, and was replaced by the P153 for the 1970 season. The P139 made one final appearance, at the 1970 South African Grand Prix, driven by George Eaton, who was effectively paying for his drive, and thus did not receive a 'works' P153. [4]

Gilby Engineering was a British general engineering company owned by Syd Greene. Greene had lost an arm in a bicycle accident at 16 but went on to compete in many UK speed trials very successfully in the early 1950s. After he stopped competing, he fed his enthusiasm for motor racing by founding a motor racing team named after his company and later constructing the Gilby racing car. The team competed in 12 Formula One World Championship Grands Prix, including 6 with cars of their own construction, but scored no World Championship points. The Gilby cars were constructed by Syd Greene for his son Keith to drive, having previously entered a Maserati 250F for Roy Salvadori and Ivor Bueb and also a Cooper for Greene Jr. Keith Greene later became better known as a team manager in Formula One and sports car racing. Gilby made its debut in the 1954 French Grand Prix with the Maserati, for Salvadori, who also drove for the team in 1955 and 1956, and the team's last event was the 1962 Italian Grand Prix. After the team ceased competing in Formula One, the final Gilby car was purchased and entered in three events in 1963, by privateer Ian Raby. Keith Greene achieved a third-place finish in the non-championship Naples Grand Prix of 1962, with the BRM-engined car, behind the works Ferrari's of Willy Mairesse and Lorenzo Bandini.

<span class="mw-page-title-main">BRM P261</span> 1960s British Formula One racing car

The BRM P261, also known as the BRM P61 Mark II, is a Formula One motor racing car, designed and built by the British Racing Motors team in Bourne, Lincolnshire, England. The BRM P261 was introduced for the 1964 Formula One season, and its design was an evolution of Tony Rudd's one-off BRM P61 car of 1963. The P261 had a relatively long racing career; variants of the car were still being entered for Formula One World Championship Grands Prix as late as 1968. During the course of their front-line career, BRM P261s won six World Championship races, in the hands of works drivers Graham Hill and Jackie Stewart, and finished second in both the Drivers' and Constructors' Championship standings in 1964 and 1965. Stewart, Hill and Richard Attwood also used works P261s to compete in the Tasman Series in 1966. The BRMs dominated, with Stewart winning four, Hill two, and Attwood one of the 1966 Tasman Series' eight races. Stewart also won the title. The works-backed Reg Parnell Racing team returned in 1967 with Stewart and Attwood, where Stewart added another two wins to his tally. In terms of races won and total championship points scored, the P261 was the most successful car in BRM's history.

It was powered by a 3.0-litre V12 engine, with a claimed output of 488bhp. London-based Swiss watchmakers Rotary Watches provided sponsorship money. The car failed to score any points during the season. The team made a total of nine entries during the season, but only qualified in one instance, at the 1977 Brazilian Grand Prix. Driven by Larry Perkins, the car retired on lap one due to overheating. Its qualifying time was six seconds slower than that of the second-to-last starter. One British journalist in Brazil exclaimed that he was ashamed of being British. The car failed to appear at the season opening Argentine Grand Prix because it was too wide to fit in the hold of the aircraft that was going to transport it to South America.
