Stores reference 5C/1252. Set of twin toggle switches for the magnetos on AVRO Lancaster and other wartime four-engined bombers. Complete with the 'gate/cage' that worked in conjunction with the undercarriage indicator and prevented the switches from being turned off when the undercarriage was retracted. Light wear and paint chipping but in very good used condition. Boxed but has probably been repackaged at some stage. Stock code M16489.
