An excellent set (of three) porcelain & bakelite electrical aviation switches.
Circa - 1920 - 1930's.
In virtually 'as new condition', having perfect bakelite covers and porcelain bases.
Identical to switches first utilised on WW1 British aircraft as magneto switches or for similar applications.
Due to surplus stock post WW1, switches such as these were re-stamped by the Air Ministry and used into
Very clearly marked with Air Ministry / Kings Crown codes and rare to find without damage.
