In late 1940, the US military opened a competition for what would become the M1 Carbine - a rifle that needed to use the .30 Carbine cartridge and weigh no more than 5 pounds (2.27kg). No fewer than 9 companies and designers entered the first round of competition in April 1941, including John Garand, Val Browning, Eugene Reising, Auto-Ordnance, and George Hyde. Hyde's entry was one of the best performers, and just a few changes to it were requested.

A second round of trials was held in September 1941, and this is one of the 5 Hyde carbines made for that second test. Unfortunately for Hyde, while he had made the changes requested, he had also managed to make the gun less accurate, less reliable, and more difficult to disassemble than his first version. Winchester would ultimately win the competition, with a rifle designed in an amazing 34 days.
