This hand-held signalling lamp could have had a number of uses. It could have been used by groups such as the Boy Scouts or most likely was used by local air raid wardens and other military personnel in World War Two. Its large face and the reflecting mechanism would have made it useful over a long distance.
This lamp is of historical interest and is retained for display and research purposes.
This is a cylindrical metal lamp with a clear glass front attached to the lantern by metal screws. The lantern has been painted black. There is an electric bulb behind the glass and a reflector disc behind the bulb. A handle, attached to the metal body, has two strands of electrical wiring at its end. The handle includes a finger clip, which, when pressed, produces a signal inside the glass area.
