Tilling Group

The Tilling Group was one of two conglomerates that controlled almost all of the major bus operators in the United Kingdom between World Wars I and II and until nationalisation in 1948.

Tilling, together with the other conglomerate, British Electric Traction (BET), became the main constituents of the country's nationalised bus industry in the late 1960s and was sufficiently well known to have entered popular culture as part of London's Cockney rhyming slang (Thomas Tilling = shilling).

The company continued as an industrial conglomerate after nationalisation of its bus interests; it was acquired by BTR plc in 1983. Provided by Wikipedia
