Planet
Planet were motorcycles produced circa 1919 to 1920.
This short-lived make made a failed attempt to exploit the post-war market. They used the 269cc Villiers engine, plus various sizes from Union and Blackburne. The rest of the machines were built from whatever components were available at the time and were typical of the period.
