Armstrong Motor Co, of 14 Ryland Street, Birmingham
Armstrong produced motorcycles from 1913 to 1915 - also see Armstrong 1913-1915
1913 The company produced a model of advanced design, powered by a four-stroke 2.75hp, 349cc Villiers engine. It had a unit-construction, two-speed gearbox, overhead inlet valve, and timing gears on the left of the engine. The rest of the machine appeared to be fairly conventional.
1914 Use of the previous Villiers engine was discontinued and replaced by the 269cc Villiers commonly used by many other firms. It had petroil lubrication and a two-speed gearbox. A single-speed version was also listed.
1915 Manufacture of the above two models continued that year, after which production ceased.
