Olivos
From Graces Guide
Olivos was a motorcycle produced circa 1920 to 1921.
This was a very short-lived marque that appeared after the end of the Great War. It differed from most others of the period in that a 499cc Blackburne engine was fitted in preference to the usual Villiers. It also had a spring frame. Production would have been limited by the availibility of the engine and other components.
