Thanks LK, that's sort of what I figured also. Made for Carlos Gove and his info engraved on the parts prior to shipping to him.
I agreed to buy this ML shotgun as the Gove connection interested me and the price was modest (I think). It wont get here for probably a week to 10 days, but then I'll break it down to check proof marks and post what I find. I don't collect shotguns, but have other guns connected to Carlos Gove's Denver Armory, so it will find a place here.
