I've had this laying around in my garden for many years as it's a bit too heavy for the collection. It's a solid shot 6" diameter with no internal cavity. I'm not sure how much it weighs but it seem to be a lot heavier that it should be for it's size. As can be seen from the photos the drive band is missing and the tip is sheared off. I assume it's probably naval but I can't see any markings that would identify it. Amy ideas?
