The 10/12 HP was one of the last successful cars built by this Manchester-based company dating from 1897. In 1924, after a turbulent life typical of the period, Belsize went bankrupt.

Another typical aspect of the company’s history was its development from a bicycle concern, through manufacturing under licence from a foreign firm (in this case the French Hurtu), to being a fully-fledged car-manufacturing company. It is worth noting also that Hurtu in turn developed its cars from the German firm Benz.
In 1903 Marshall and Company became the Belsize Motor and Engineering Company, and it straight away tried to change its production. However, it could not give up foreign engines that quickly, and it improved and developed those that it used from the Paris Société Buchet. Almost immediately after becoming independent, Belsize was offering single-, twin-, 3-, 4-, and 6-cylinder cars. This variety of engines shows again how Belsize faithfully reflected the uncertainly of the market. Mass-produced small cylinder capacity cars became the order of the day, however, and those firms that could not cope with the new market requirements ceased production.
