This, "I think," is the best of the tubes I received from the box of many old electronic idems. Showing of days starting the vacuum tubes/values. Wish I could find more info on it so I could see it give its glow, but I decided to let someone with the knowledge try. See the pictures and see all of the original ways this was put together. With glass, brass/copper, and a plastic/bakelite like base. Will over pack for shipping. Hope it could stay in the USA. You can pick it up here or ebay me if you want it shipped differently than I selected. Thanks
