The first all-new models introduced by the Austin Company after the Second World War were the A125 Sheerline and A135 Princess models of 1947. These were large luxury saloons, the first Austin cars with independent front suspension and hydraulic brakes and fitted with an overhead valve engine derived from that used in Austin’s truck range.

The Princess model had a coach-built body made by the Vanden Plas Company of London, which Austin had acquired in 1946. In 1952 the Sheerline was replaced by a Vanden Plas Princess limousine. This basic model continued in small scale production for 16 years and almost monopolised the limousine market. It was used by undertakers, as well as numerous dignitaries and official organisations.

A substantial number were also used by the Royal household over the years and, when production of the model was about to be stopped in 1968, two of the last cars were specially set aside for Royal use. The limousine on show is one of these two cars and has transported many of the current Royal family.
