Canadian R.E.L. Type 7 Vacuum Tube (U.S. Type 4C27 / British CV92) NOS in Original Box

New old stock Canadian military R.E.L. Type 7 vacuum tube, equivalent to the U.S. Type 4C27 and British CV92, manufactured for Research Enterprises Ltd. (R.E.L.) by Rogers Radio Tubes Ltd. during World War II. Still housed in its original factory carton with inspection markings, serial number, and military labeling intact. These tubes were produced for Allied military radar, communications, and electronic equipment used by Canadian, British, and American forces. An excellent original example for collectors of WWII electronics, vacuum tubes, military communications equipment, or early radar technology. Box shows expected storage wear while preserving the tube in original new old stock condition.
