I wonder if the bottom of the metal box is missing? With the green color it looks to be a army box!.What's bottle in it could be anything? Unless you can get the stuck bottle unstuck from the top of the case you might never know for sure.You never know either you can find it on the internet.
I once found a coke cola bottle in the desert.The bottle entire surface was frosted.The com[pany wasn't known for frosted surface bottles.The desert sand did this because of the wind and the sand frosted the bottle.One thing to remember is that frosted bottles look "old" so many people would see...
The reason for the "bottle not to be sold or never sold" embossed on the bottle is that the bottle had to be returned to the place they bought it from.The.Company's wanted to keep down the manufacturing prices on the bottles.(no there wasn't any deposit money back bottle then.)
