These are the REAL THING! Made by Tung-Sol/USA in the late 1950's. Mostly 1959 batch, but still as new in original military boxes as the current production re-issue ones. These are military stock tubes with long ribbed plates and square-getter on top in almost pristine condition. Matched pairs available.
