Here is an oldie! It's a wave meter with 3 plug in coils. You measure wavelength or frequency by tuning it while it is closely coupled to a tank circuit in a transmitter while it's running. When you hit the frequency that the transmitter is operating on, the lamp will light up. The three coils that come with it are labeled on their original boxes as 101, 102, and 103. I'm not sure which ranges these are but the it appears to cover from 1.8 to 500 Mc (MHz) according to the dial calibration. It is in excellent condition
