Armstrong Siddeley New 20hp
The Armstrong Siddeley 20hp motor car first released in 1921 was continually updated, however, when a completely new engine was released in 1931 the model became known as the New 20hp. Available with either a Short or a Long wheelbase, they both offered a smooth and comfortable ride. The 3190 cc, 6-cylinder OHV engine provided sufficient power to propel the sumptuously appointed body of almost two tons effortlessly. Like all Armstrong Siddeley cars, they were equipped with a Wilson self-changing gearbox.

The following images of a 1932 20hp Town and Country Saloon is a car that many enthusiasts consider to be the most original and unmolested pre-war Armstrong Siddeley. Note the original glass that has mellowed with age to carry a yellow tinge, the paintwork is the original cellulose whilst the engine is robust enough to have enabled the previous owners to embark on continental touring holidays in it.
