Thompson SMG in 30 Carbine
Ian McCollum of Forgotten Weapons provides an expert examination of an experimental Thompson SMG chambered in .30 Carbine, housed at the Cody Firearms Museum. This prototype, serial number 1, showcases modifications to the receiver and a unique double-stack magazine to accommodate the Winchester-developed cartridge. Despite its potential, the weapon failed military trials primarily due to exceeding the weight requirement.
