1919 - 1920
The 11/22hp Hammond was made by several ex Arrol-Johnston employees. Its cylinder bore of 69mm was shared with many other light cars, whose 100mm stroke gave a capacity of 1496cc. The Hammond, however, had a 150mm stroke, so its capacity was 2242cc, yet the owner paid a tax on only 11.9hp. The specification included a 4-speed gearbox, worm-drive rear axle and cantilever rear springs. The makers took a former aircraft factory on a 50 acre (20.3 hectares) site, and had amibitious plans to make vast numbers of cars. Nothing came of these, and probably no more than a few prototypes were made.
