The Daimler is still the favourite car of kings: in mid-April 1931 it was announced that the King of Siam had just taken delivery of a 20/30 hp Daimler sports saloon bodied by Arthur Mulliner of Northampton. King George V took delivery of five new Hooper-bodied Daimlers, which he had ordered in October 1930. Three 40/50 hp Double-Six limousines and two 30/40 'enclosed limousine' each for the King and Queen - are the first Royal cars to be fitted with safety glass. One of the most sumptuously finished DoubleSix Daimlers was delivered to His Highness the Maharajah of Bhavanagar. A Connaught enclosed-drive limousine painted coronet red and black and all the brightwork - including the radiator - is silver-plated. The passenger compartment is upholstered in red and gold silk tapestry, with a gold pile silk headlining, all the woodwork is in macassar ebony, and the ventilation system, controlled by flaps concealed in the roof, incorporated cages containing scented cotton wool to perfume the air in the rear compartment.
