Pulled this item out of roughly 60 feet of water at a flooded quarry today while magnet fishing. It's marked, "MARBLE'S GLADSTONE, MICH. USA," and "30 GOV." I believe it may be a headspace guage for the government .30 caliber carbine, but I cant find any examples of this style anywhere. Any ideas would he greatly appreciated. Thanks!
