After the end of the war the 11.1 continued with a larger, 1,400 cc, engine and standard electric lighting as the 11.9 until 1923 and the updated 12 until 1926. Following Wilbur Gunn's death in 1920, three existing directors headed by Colin Parbury took charge. The first of the company's sports models was launched in 1925 as the 14/60 with a twin-cam 1,954 cc four-cylinder engine and hemispherical combustion chambers. The car was designed by Arthur Davidson who had come from Lea-Francis. A higher output engine came in 1927 with the two-litre Speed model which could be had supercharged in 1930. A lengthened chassis version, the 16/65, with a six-cylinder 2.4-litre engine, was available from 1926 to 1930. Their final car of the 1920s was the three-litre using a 2,931 cc six-cylinder engine. This continued until 1933 when the engine grew to 3,181 cc and was also available with a complex eight-speed Maybach transmission as the Selector Special.
