1913 Prototype built with a two-stroke engine with four cylinders arranged in pairs, and each pair shared a common combustion chamber – a doubled-up version of what would later be called the "split-single" engine. The pistons in each pair drove the crankshaft together as they were coupled to it by a V-shaped connecting rod. For this arrangement to work, it is necessary for the connecting rod to flex slightly. The claim was that each engine had only seven moving parts, four pistons, two connecting rods and a crankshaft. This was connected to a two-speed epicyclic gearbox, to simplify gear changing, and a chain to the rear wheels.
1914 Formed as a private company.
In 1914 he moved to Vicarage Road, Croydon where a second prototype was built. The business was renamed Trojan in 1914 but he lacked the capital to start production.

In April 1920 Trojan advertised that they were prepared to enter a licensing arrangement and by June were talking to Leyland Motors. A deal was made in 1921 for Leyland to make the Trojan car, paying a royalty of £5 for each car. Production was slow during 1922 but picked up in 1923 and around 17,000 were built altogether.

The company acquired the rights to build the Elva Courier sports car in 1962,[6] producing 210 cars between 1962 and 1965 when production switched from road cars to the McLaren-Elva racing car.
