Yeah, I thought the same thing... a "Wamoscope?"
Was it produced by the Wham-O toy company
that makes the Hula Hoop, the Frisbee, the Super Ball, and Silly String? Wham-O was founded in 1948,
so why not? Actually, Wamoscope is derived from "WAve-MOdulated oscilloSCOPE." It combined a traveling-wave
tube with a cathode ray tube in single enclosure.

Simplified Radar to Use "Wamoscope"
Radio engineers attending the Western Electronic Show in Los
Angeles recently were amazed to hear of a single-tube radar set. Developed by Sylvania Electric Products,
Inc., for the U.S. Navy, the radar has been dubbed the "Wamoscope." Literally interpreted, "Wamoscope"
means "WAve-MOdulated oscilloSCOPE." Microwave radar signals can be fed directly into the tube wherein
a single glass envelope-they are amplified, detected, and finally displayed on a fluorescent screen.
Secret of the "Wamoscope's" unusual ability is the traveling-wave focusing principle. (The focusing
solenoid is shown in the photo as the metal cylinder.) The "Warnoscope" can be designed for any u.h.f.
band and with any size cathode-ray screen. Although the first one is reserved for the military, radio
engineers are planning on possible applications in miniaturized commercial and industrial closed-circuit
First "Wamoscope" measures just under two feet but contains complete radar reception system for direct
signal display on cathode-ray screen on end of tube.
