This was the first Armstrong-Siddeley fitted a flat radiator in place of the vee which was fitted to the larger cars. The car and sold well.
In June 1925 appeared the 4/14 hp Mark II . The car was slightly larger than its predecessor, but engine and other technical characteristics remained the same., Among improvements were front wheel brakes and a longer chassis, while bodies were lower and more attractive.
