Scammell Lorries introduced its "Mechanical Horse" in 1934. Built for the London and North Eastern Railway, the vehicle was designed by O.D North.
This was a large 3-wheeler with wooden cabin mounted on a steel chassis, available with either a 3 ton or 6 ton payload capacity.
Powered by 1125cc and 2043cc engines (for the 3 and 6 ton models respectively), they had a single front wheel which could rotate 360 degrees making it highly maneuverable.
In 1967 it was replaced by the Scammell Townsman which ceased production in 1968.
Note: The Scammell was also made under licence in France by Chenard-Walcker as the FAR Pony Mécanique, which utilised a Citroen engine.
