Riley 12hp Saloon. (1939-40)

Riley 12 Saloon

With the takeover of Riley by the Nuffield group in 1938, the entire model range was revised, and reduced to the 12/4 and 16/4 engines. There were also only 2 body styles available on each chassis - a 6-light 4-door saloon with swept tail, or 2-door drophead coupe. The Saloon at least had started development before Nuffield took over, and was a clear development of the Adelphi body style. Approximately 550-575 Saloons were built.
The wings were the newly fashionable helmet style, rather than traditional Riley flowing designs, and the rear doors were rear hinged in place of the Adelphis centrally hinged doors, The rear of the car was also squarer, with a larger rear quarter light and larger trunk.
