Riley was a British motorcar and bicycle manufacturer from 1890. Riley became part of the Nuffield Organization in 1938 and was merged into the British Leyland Motor Corporation in 1968. In July 1969 British Leyland announced the immediate end of Riley production, although 1969 was a difficult year for the UK automotive industry and many cars from Riley's inventory may have been first registered in 1970.

Nuffield Organization was the unincorporated umbrella-name or promotional name used for the charitable and commercial interests of owner and donor, William Morris, 1st Viscount Nuffield. The name was assumed following Nuffield's gift made to form his Nuffield Foundation in 1943, it linked his business interests to his existing very generous philanthropy. The same enterprises had previously been referred to as the Morris Organizations and at first described itself as The Nuffield Organization, A Cornerstone of Britain's Industrial Structure.
