This is a fun little pen light flashlight from the late 60s or early 70s. Made with aluminum and a opaque red tip, the lightbulb still works. You just have to slightly twist the pin to get the connection to turn the light on and then untwist to loosen the connection to turn the light off. it is not a super sturdy design and if you jostled it around in your pocket long enough, I’m guessing it would come unscrewed but this is more for a decorative desk piece or even to put in a drawer when you need a little flashlight for emergency purposes. See photos for exact details. Thanks for looking.
