Homer T Severin had been a car dealer since 1906, when he decided in 1920 that he want to build cars rather than sell them. The Severin Motor Company was established in St Louis, MO, with the Model H commencing production in July 1920. The Model H was a typical assembled car of the era, and was powered by a 6-cylinder Continental engine.
In mid-1921, Severin announced that he was going to relocate the factory to Oakland, CA, but didn't perform the required paperwork and documentation. After getting in trouble over this, Severin decided to get out of the car manufacturing business. The factory in St Louis was taken over by the Metropolitan Motors Corporation, with production continuing until early 1922 to use up parts that were on hand. Total Severin production was approximately 300 cars.
