Received from my 82-year-old friend that collected everything electronic and radio. He had a shed in his backyard that was larger than my house, 2 stories. Insane amount of items. He was Navy and Airforce and worked FAA until 75 years. He's doing well and still inventing things! There is NO bulb inside. The black rubber gaskets will need to be replaced. Please see the photos for a visual description.
