Sir W G Armstrong Whitworth & Co Ltd was a major British manufacturing company of the early years of the 20th century. With headquarters in Elswick, Newcastle upon Tyne. Armstrong Whitworth built armaments, ships, locomotives, automobiles and aircraft.
The first Armstrong Whitworth automobile was manufactured in 1904, when the company decided to diversify to compensate for a fall in demand for artillery after the end of the Boer War. It took over construction of the Wilson-Pilcher, designed by Walter Gordon Wilson, and produced cars under the Armstrong Whitworth name until 1919, when the company merged with Siddeley-Deasy to form Armstrong Siddeley.
