Lots of G-1's have patches but the nice thing is that one can locate almost any USN/USMC squadron patch on the bay and add it to the jacket. I know some say "never patch an original" but why not? I think many USN/USMC nameplates get removed post service and maybe folks go ahead and remove patches seeing as the jackets look a bit "off" with squadron patches and no nameplate.
