The Wolseley Ten was a light saloon car produced by the Wolseley Motor Company in 1939 and 1945 to 1948 . The ten horsepower class of cars was an important part of the market in 1930s Britain and Wolseley entered the sector with their 10/40 of 1936 based on the contemporary Morris Ten. Both Morris and Wolseley were part of the Nuffield Organisation. The 10/40 ceased production in 1937 and it was not until February 1939 that Wolseley introduced a new car the Ten.
