Vickers-Armstrong produced the first of these cheap and simple tracked vehicles in 1932. They were hardly ideal military vehicles, but they were of very straightforward
construction and fitted with a common Ford 4-cylinder 52hp engine. They were advertised as being capable of a wide variety of tasks and sales were good.
The vehicles themselves were only 7-foot long and 4-foot wide so were very compact. They were also very cheap at around £375 each and were a cheap way of introducing
mechanisation to various armies around the world. Once in service they were widely used as cross-country supply vehicles towing trailers as well as gun tractors and support
weapons carriers.
