I spotted your cool embossed cork top bottle as a winner even before I saw your link. Finding where the outhouse was would be the major score. Many a whiskey bottle got dropped in them to conceal them, everything else decayed, and voila a treasure trove. Out here, finding one that has not already been dug is rare.
If you have a picture of the barbed wire it is very likely i could identify it for you, when made, etc.
