Arrol-Johnston of Paisley
1898 Advertisement. 'The Mo-Car Syndicate will exhibit a horseless carriage...'
1901 Mention of an Arrol-Johnston 6hp light car entered in a race by the Motor Car Syndicate 
The first Arrol-Johnston car was a six-seater "Dogcart" (a vehicle with two transverse seats placed back to back), which went into production at a factory at Camlachie, in the East End of Glasgow.
The Dogcart was a wood-bodied vehicle powered by a 10 hp flat-twin horizontally opposed engine with four pistons mounted beneath the floor, which was started by pulling on a rope. The vehicle boasted chain final drive and its high-wheeled, solid-tyred, horse-carriage type of body was retained well into the 1900s. The brakes were arranged in the form of shoes which could be pressed on the back of the solid rear tyres, and the suspension comprised full elliptic leaf springs at the front, and half-elliptics at the rear. Transmission and brake control levers were mounted close to the driver’s right hand.
1901 The company's Camlachie premises were destroyed by fire and production was moved to Paisley.
1902 William Beardmore took the largest single shareholding in the company, creating a captive customer for his iron and steel components. He later became Chairman when A-J (as it was widely known) became a public company.
1902 John S. Napier appointed Managing Director
1903 'The Mo-Car Syndicate which works the Arrol-Johnston patents...'
1903 A-J was restructured financially. New finance, mainly from Beardmore, became available, Beardmore wishing to help the firm stave off bankruptcy, and there were important changes in staff, including the arrival of John S. Napier. George Johnston left as a result of a disagreement and founded the All British Car Co, a venture that was to be short-lived. A-J became effectively a wholly owned subsidiary of William Beardmore and Co

1913 Arrol Johnston bought land at Heathhall, just outside Dumfries, and commissioned an American firm to build a factory. Claimed be the first factory in Britain to use ferro-concrete, and was designed by Albert Kahn, architect of the Ford factory at Highland Park, Michigan, where the Model T was produced.
A-J contracted to build 50 electric cars for Edison at the new plant but it is not certain how many were actually made.
Several models of car including the six-cylinder 23/9 were built up to the outbreak of war.
1914 November' Details of the new 17.9hp car. Also 15.9hp and 20.9hp models.
The authorities brought Frank Halford back from France to develop the 160 h.p. Beardmore engine with a view to designing a more powerful unit, which he did with Arrol-Johnston in Dumfries. The outcome was the B.H.P. (Beardmore-Halford-Pullinger) — a 230 h.p. vertical six-in-line water-cooled engine embodying cast-iron cylinder heads, steel cylinder liners, and sheet-steel water jackets. In the B.H.P., Halford departed from the practice of using single large inlet exhaust valves, and used two small exhaust valves and a single large inlet valve per cylinder. The design was turned over to Siddeley-Deasy, who changed the cylinder heads and water jackets to aluminium and the name to Puma. They made over 6,000 Pumas.
