Policeman’s Billy Has Built-in Flash Light (May, 1939)
Policeman’s Billy Has Built-in Flash Light
Flash light and night stick are combined in a single unit that leaves policemen and watchmen with one free hand in nighttime emergencies. The wooden billy, strong and rugged in construction, is hollowed out to accommodate two dry cells and a light bulb that throws a beam from the end of the stick when a built-in switch is pressed. The bulb, lens, reflector, and cells are well cushioned to withstand severe shocks and rough handling.
