The De Bolotoff SDEB 14 was a British two-seat utility biplane designed by Prince Serge de Bolotoff and one example was built at his de Bolotoff Aeroplane Works at Sundridge Aerodrome, Sundridge, near Sevenoaks, Kent.
The silver wave bearing three ravens represented the River Ravensbourne, while the sun was for Sundridge.
One of his apprentices was Nicholas Tapsfield, who was later to work at the paper mill at Sundridge.
There are no large communities along the route between Parry Sound and Sundridge, however there are several small communities including Waubamik, McKellar, Dunchurch and Ahmic Harbour.
