Hello, I was looking for whether the F2G was ever planned to have 4x20mm M3s when I stumbled upon the F2G's Japanese wikipedia page, and in the variants section there was a F2G-3 that is described to be "A tentative name for an expanded and improved version proposed by Goodyear in response to the development results of the F2G. Also known as "F3G." Only a proposal." There was no footnote for the paragraph. Does anyone have any info on this variant? And were the F2G's ever planned to have 4x20mm M3s?
