Flashlight Used as Field Phone (May, 1934)

What, no camera?

Flashlight Used as Field Phone

A COMBINATION flashlight, telephone and telegraph device may be hooked in on telephone or fence wires to provide field communication.

Operating on a two-cell flashlight battery, the device has receiver and transmitter in one. It has a folding telegraph key for code signals and a flashlight lamp for copying messages at night.
