William Beardmore & Co Ltd was one of Scotland’s largest steel producers in the late 19th century, and also built battleships at their yards at Dalmuir. Sir William Beardmore was the largest shareholder in Arrol-Johnston from 1902. The firm supplied chassis to Arrol-Johnston (and other car makers), and he kept an interest in the company up to its demise in 1929. Beardmore made aero-engines and 650 complete aircraft during World War I, and in 1919 they launched their own cars. It was an ambitious range of three different cars each made in a different factory.
Vehicle production ended in Scotland in 1929, but taxis were continued in a London factory which had been the service centre for Beardmore cars. This lasted up to 1967.
