BSA were a division of the Birmingham Small Arms company who diversified into making motorcycles (1905) and motor cars (1907). But in 1910 BSA bought out the Daimler Motor Company and the next BSA cars were no more than Daimler small cars with 'BSA' badges. From 1922 to 1926 BSA produced a small number of light cars of its own design utilising a V-twin engine derived from Hotchkiss design (a smiliar engine was produced with differences by Armstrong-Siddeley for its own 'Stoneleigh' cars). In 1929 BSA tried again to produce a light car, this time producing a front wheel drive three-wheeler with independent front suspension, and the vee-twin 1,021cc engine adapted for the front wheel drive configuration. The first models were sold as a Tourer or as a Special Sports, but a 4-seater 'Family' was soon introduced. Improvements were made each year and in 1933 a new three wheeler was offered with a 10hp 4-cylinder 1,075cc engine, but the 9hp model continued to be sold in parallel. Later the 10hp engine formed the basis of the new BSA SCout 4-wheeled car. Three wheeler production continued until 1936.
