Rolls-Royce Phantom IV by H. J. Mulliner from 1956. H. J. Mulliner & Co. was a well-known British coachbuilder operating from Bedford Park, Chiswick, West London. The company which owned it was formed by H J Mulliner in 1897 but the business was a continuing branch of a family business founded in Northampton in the 1760s to hire out carriages. In December 1909 the controlling interest in this company passed to John Croall & Sons of Edinburgh. Croall sold that interest to Rolls-Royce in 1959.
