Vintage American-made Raytheon 4J63 magnetron clearly marked “USAF-4J-63,” “A0975D,” and “RAYTHEON MADE IN U.S.A.” The 4J63, also identified as the QK62 type, is a tunable magnetron used in radar jamming and electronic countermeasure equipment.

The open mounting arrangement provides an excellent view of the mechanism, making it an attractive display piece for collectors of military electronics, Air Force equipment, and early microwave technology.

Wooden base shows handling wear and handwritten identification markings. Exact manufacture date and original equipment assignment have not been established.
