Thompson SubMachine gun. Known by dozens of different nicknames, instantly recognizable by most everyone in the last 7 decades or so, even those not 'in to guns', too late to make it's intended debute in WW1, languished unwanted till the USPO, of all people, made the first gov't purchase of them. Used by every branch of our armed forces and just about every other govt around the world (free world and otherwise), Law Enforcement, outlaws, ranchers, farmers, gangsters, security, and just plain gun owners. Still in use, extremely collectible and expensive as all hell.
