H. J. Mulliner & Co. was a well-known British coachbuilder operating from Bedford Park, Chiswick, West London.
Robert Bouverie Mulliner had first established a thriving coachbuilding business in Liverpool in the mid-1850s then sold that to his brother and in the early 1870s started another in Chiswick on the outskirts of London.
[3] In 1906 the London works were moved from Mayfair to Chiswick and in December 1909 H J Mulliner sold a controlling interest in the company to John Croall & Sons of Edinburgh.
[4] A family connection was maintained as Croall employed H J Mulliner's wife's brother, Frank Piesse (1885–1960), to run the company.
[5] A financial columnist noted that the (cash) outlay for Rolls-Royce was relatively small as the net assets of John Croall were around £250,000.
