Notes
Announced in The Cycle and Motor Trades Review of October 14th 1909, this was Calthorpe's first foray into motorcycles, despite a long history of cycle making dating back, via George Hands' Bard Cycle Co, to 1895. Cars had been added to the range in 1905.
The White and Poppe engine seems to have been a stop gap as by March 1910 it was in process of being superseded by a new 'Calthorpe' engine, in reality one of F E Baker's 'Precision' range, a company with which Hands was to have dealings until after the First War.
