Armstrong made motorcycles from 1902 to 1905
This machine was typical of the primitive designs of the era. It had a small Minerva 211cc engine that hung from the downtube of a heavy-duty bicycle frame fitted with rigid forks. As an assembler, the company bought in parts - the frame lugs came from Chater-Lea.

Possibly another company of the same name made Armstrong motorcycles between 1913-14
