her parents placed severe limitations on their relationship, and it was not until 1938 that they were able to marry. Auto racing Bira first raced with his cousin Prince Chula's team, White Mouse Racing, driving a Riley Imp at Brooklands in 1935. In this car Bira established the national motor racing colours of Siam: pale blue with yellow. He later lived near Geneva, Switzerland, and in the south of France. Later in 1935, Prince Chula gave him one of the new ERA voiturette racing cars—R2B, which was nicknamed Romulus. Bira finished second in his first ever race in Romulus, despite needing to stop for repairs. The remaining races of the season saw Bira consistently placing among the more powerful Grand Prix vehicles, with another second place, and fifth at the Donington Grand Prix. For 1936 the princes decided that the previous season's results merited a second ERA. They purchased chassis R5B (which Bira named Remus) to use in British events and retained Romulus for international races. Chula also purchased a Maserati 8CM to complete the White Mouse roster. Bira's expertise behind the wheel earned him the Coupe de Prince Rainier at Monte Carlo. Bira won a further four races in the ERAs that season, and took the Grand Prix Maserati to 5th at Donington and 3rd at Brooklands. This was the high point for Bira and the White Mouse team. Following Dick Seaman's move to Mercedes for 1937, the Thais purchased his Grand Prix Delage and all of its spare parts, along with a second Delage. Despite several upgrades, and hiring experienced race engineer and future Jaguar team manager Lofty England, the cars underperformed, and on many occasions Bira raced in the older and by now substantially inferior ERAs. In addition, the money spent on the Delage upgrades had sapped the resources of the team and corners were being cut in the ERA's race preparations. Later in the year White Mouse did invest in a newer C-Type ERA, chassis R12C. R12C came to be known as Hanuman, and Bira attached a large, embossed, silver badge depicting the Hindu deity after whom he had named the car. Following a major accident in 1939 Hanuman was rebuilt back to B-Type specifications, and in light of this major overhaul Bira renamed the car Hanuman II. While Bira maintained a respectable results tally in British events, the more costly international races were largely a
