In short the factory name was ÅSSA. It was founded 1907 but got its current name 1932. The main production was railroad switches and railroad signal systems. ÅSSA closed 1987.
An early car production started in 1911 and the only surviving car can be seen at the ÅSSA museum which is in the same building as the factory once started.
