Park Ward was founded in 1919 by William MacDonald Park and Charles Ward; they had worked together at F.W. Berwick Limited, the makers of
Sizaire-Berwick cars. They built their first Rolls-Royce body in 1920. By 1930, 90% of all of Park Ward's efforts were for Rolls-Royce. After the Rolls-Royce take-over of Bentley in 1931, Rolls-Royce took a stake in Park Ward. Beginning in 1933, when they obtained patents, Park Ward developed a technically interesting all-steel saloon in conjunction with Rolls-Royce, and from 1936 offered it on the
4¼-litre Bentley chassis. After
World War II, Park Ward continued to produce special coachwork, and the all-steel technology was used by Rolls-Royce to produce a standard body range on its cars, starting with the
Bentley Mark VI. Mulliner Park Ward operations were centralised in the former Park Ward factory in
Willesden. In 1971, the division was retitled Rolls-Royce Motors Ltd. ==Bugatti Royale coachwork==
