WWII U.S. Navy TS-251/UP Radar Test Set with Original Transit Case – July 1945

Original World War II U.S. Navy TS-251/UP Radar Test Set, manufactured in July 1945. Designed to test and calibrate pulse radar and radio navigation equipment, this specialized electronic instrument features selectable output levels, channel selector, pulse/CW operation, built-in pulse delay reference chart, and original military data plate.

The unit remains housed in its original heavy-duty transit case and retains its original wrinkle-finish panel, accessory compartment, and spare crystal container. The front panel still displays its original wartime “MFD JULY 45” acceptance marking, making it an attractive display piece for collectors of WWII radar and military electronics.

A scarce and highly desirable example of late-war U.S. Navy electronic test equipment.
