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 TV systems.
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.
