File:ERA R12B Hanuman II.jpg

English: Prince Bira of Siam's English Racing Automobiles R12B racing car, "Hanuman II", pictured in the national racing colours of Siam (later Thailand) of pale blue with yellow chassis and wheels. This photo appears to have been taken at a historic race meeting some time in the 1980s. In the late 1930s Prince Bira and his cousin Prince Chula of Siam owned three ERA cars. Hanuman was their third, and the first to wear the blue-and-yellow of Siam in place of Prince Bira's earlier single colour "Bira Blue" scheme. All were run by their Whitemouse Garage racing team, whose emblem can be seen on Hanuman II, just ahead of the cockpit opening and adjacent to this car's distinctive raised 'Hanuman' emblem in silver. R12B was rebuilt as a C-Type car in 1937, and renumbered R12C, prior to being sold to Chula and Bira who named it "Hanuman". However, following a major accident in 1939 the car was rebuilt again and reverted to a B-Type chassis. It was thus renumbered back to R12B, and in light of this major rebuild Bira renamed the car "Hanuman II". As of 2007 this car is the property of the King of Thailand. This car is not to be confused with R12C Hanuman, which was built in the 1980s using the damaged C-Type chassis and discarded parts from the post-accident rebuild that formed Hanuman II.
