Description

This object consists of two cardboard carriers of 100 bulbs each as supplied by the factory. The carriers have 100 holes punched into them, into which the very small incandescent lamps fit.

Each lamp consists of a round plastic knurled knob with brass threads extending from one end. At the end of the threads, there is another contact insulated from the threads by a plastic collar. A bulb approximately 5/32 inch in diameter and 1/4 inch long extends from the collar. The bulb is intended to be threaded into its socket from the back of a panel.
