A good late WW1 twin lever magneto / ignition switch by Lektrik.
Circa - 1917.
In good untouched original condtion, with positive action from both levers.
The brass 'bell cover' having no dents or cracks, and porcelain base without
damage. It would polish well if required.
There are no markings on the outer base, so Pre-RAF / Air Ministry.
This early switch is also suitable for motor cars with twin ignition
systems, such as vintage Bentleys.
