As I understand it, the G-1s were at one permitted to be either goat skin or cowhide, but the cowhide were supposed to be embossed(?) to resemble goat skin. My memory of the G-1s made during my time is that they were thick and heavy, much heavier than my slightly earlier goat skin w/ mouton collar. There may well be embossed thinner cowhide Which I'm guessing would be harder to differentiate. Not certain, however, but would kike to know when I finally get to my G-1 cache.
