Bankruptcy
Directly after the bankruptcy of Riley, the company's assets came into the hands of the Nuffield Corporation which drastically pruned and rationalized the Riley model range, utilizing components from the MG/Design
Riley still retained a lot of autonomy after their acquisition by Lord Nuffield and this car was Riley's attempt to keep up with the fashions of the late thirties with helmet-style front mudguards and a bigger boot and slightly heavy styling. In many ways it was an update of the earlier 1936 Monaco and Adelphi models. The Adelphi in particular had been very successful for Riley and so it made sense to carry this theme forward with the new model. Underneath the new body the car was an updated Riley Victor chassis (basically a Merlin chassis) with some cost savings and also some improvements. With access to the Nuffield parts bin, Riley could adopt the MG/Wolseley synchro gearbox in place of the American Borg Warner overdrive box in place of the Riley sector box. The engine, though still with gear driven camshafts, had an improved water pump. Negatives were the adoption of an umbrella style handbrake under the dash. Brake drums were smaller at 11 inches rather than the 13 inches of previous 12/4s. Springs now had rubber rather than bronze bushings. The steering was by Bishop Cam, the column adjustable for length. Springs were still semi-elliptic fore and aft. Brakes were still by the Girling rod system.Road test
John Prioleau reviewed the car for ''The Observer''. He described it as a compact car but not crowded, with plenty of room for four full-sized people. Front seats a little too upright. Nicest looking dashboard on any 1939 car. This saloon is not fast but it can cruise within 5 mph of its maximum (he reached an indicated 67 mph). The steering was light and responsive.The New 12 Riley, Prioleau, John. ''The Observer'', 27 Aug 1939: 20References
