Richard, I am assuming that yours are the dimmer types. Is the control on the light itself or is the controller in the circuit and it controls all lights on the same wire?


In the small amount of Matilda info I have, it mentions that there are "six festoon lamps" in the hull and three in the turret.
Do either of the previously mentioned interior lamps correspond to a "festoon lamp".

Jared,

Mine are dimmer type, all controlled by lever, off and progressively on.

Festoon lamps......now that has clicked my mind. I recently did the electrical work on the restoration of a 1936 Vickers light tank (ex-Aussie as it happens). According to the wiring diagram that had festoon lamps. On investigation, they were standard Lucas items as used on Bentley car dashboards, among others. Also, on inspecting the inside of a WW1 Mark IV tank hull last year, I spotted a row of them inside, only the bases though. So the design is / was old.

If you look at the attached photo of the Vickers instrument panel, one of the lamps is at the top right. The cylindrical part contains the bulb and is switched on by turning it, when the window comes around the light comes on. I feel sure the Matilda could have had the same lamps, ...............unless someone knows different
