Birmingham Small Arms Company, also known as the BSA, is an industrial group that manufactures weaponry and eventually expands into bicycle, motorcycle, and automotive manufacturing based in the northern part of Birmingham, England.
Background[]
The BSA is the main employer in Small Heath and the site of industrial discord. As one of the world's biggest small arms manufacturers, a BSA factory is a one-stop-shop for any of a street gang like the Peaky Blinders' weaponry needs. There have been a lot of strikes at the Austen works and the BSA factory lately. The newspapers are talking about sedition and revolution. Inspector Campbell is coming to Birmingham as a result to hunt down Communists.
