This listing is for an Antique DeMoulin Bros. & Co. Patented Lung Tester Practical Joke. This item was used as a practical joke at bars. A person was encouraged to blow into the metal pipe to test their lung strength and a puff of white powder was released and covered their face. A very loud bang would follow when a 22 caliber blank was triggered. This item is sold as is with no knowledge of its working condition.

Please make sure to check our listings often as we are in the process of assisting a long time collector with liquidating his collection. We have listed vintage toys, advertising, glassware and other items and will be listing more each day over the coming weeks. Thanks for looking!
