OSS "Stinger" Covert Cigarette Guns

My Father, one time, brought home a mini flare launcher. The flare was screwed into the end. It looked a lot like one of the single triple A flashlights, about the same size. It could also fire a single .22LR. This was late 60's time frame.

I saw something similar in the German Spy Museum in Berlin a few weeks ago. Thanks for sharing

CW5 Jack Cardwell I had heard of these but never saw one. Not sure I would want to carry one around. They really do not look like pens, so the chances of being clandestine seems small to me.
