AEC was a UK based vehicle manufacturer which built buses and trucks from 1912 until 1979. The acronym stood for the Associated Equipment Company, but this name was hardly ever used; instead it traded under the AEC and ACLO brands. While famously associated with the London Routemaster bus, AEC supplied commercial vehicles to many companies both domestically and around the world.
British Road Services was established in 1948 and was the company that formed following the nationalisation of Britain’s road haulage industry, under the British Transport Commission, as a result of the Transport Act 1947.
