During the 1914-18 war the Staines factory turned out armaments, largely shells.
After the war the 11.1 was put into production again. In 1920 the longer wheel base 11.9 was introduced with a larger engine of 1420 cc (69 x 95mm) featuring a separate block and crankcase and an angular honeycomb radiator. The 11.9 continued in production until 1923 when it became the 12/24 but, due to continued increases in weight, it became steadily lower geared as time went on. There were several variants, including a stark cheap model with no starter or instruments and the bare legally necessary lamps.
Wilbur Gunn dies in 1920 aged 60.
Bill Oates campaigns a special lightweight 11.9 and by October has achieved 5 1500cc records including 79.17 mph over an hour.
