be chambered for the .30 caliber Carbine cartridge. Winchester initially decided against developing a submission because of other commitments that included the Browning prototype being worked on by Williams. During the trials of the Model G30M at Quantico and San Diego, it had become apparent to Winchester they were not going to be able to replace the M1 by Garand. When Williams produced the Model G30R, it convinced Winchester they should be able to come up with a prototype for the light rifle trials. The challenge for Winchester was producing a working light rifle in time for preliminary tests pending a second set of light rifle trials. Williams had already shown he worked at his own pace, so Winchester assigned two other employees to head up the project. When Williams was not included, he was livid. Williams refused to have anything to do with the gun and did not want his name associated with it. Thirteen days after they had begun, Winchester employees completed the first prototype. The receiver, rotating bolt, slide, and short-stroke gas piston used on this first prototype were based on those used by Williams to produce the Model G30R. Of these four parts, three were designed by Williams from parts already in use on other rifles. The one part Williams could take sole credit for was the short-stroke gas piston that accessed the high-pressure gas near the breech to operate the semi-automatic action. The preliminary tests of the first prototype by the Ordnance Department on August 9, 1941, proved the design had sufficient merit for Winchester to proceed with the development and submit a light rifle by the September 15, 1941, deadline for the final trials. For the second prototype, Winchester formed a second team consisting of the two prior employees and others with Williams as the project director. Three days later, Winchester removed Williams from the team after assessment of a dispute between Williams and the others that had forced the project to a halt. The team continued the work on the second prototype without Williams, whom Winchester allowed to design his own prototype concurrent with the others. On September 12, 1941, the second prototype light rifle designed by the team was complete and ready for submission but for two problems that had yet to be resolved. Williams was asked to help the others sort out the problems, and collectively solutions were found that allowed
