its a long shot but can anyone help me identify this bottle. I dug a few of these small pontiled bases today and then one that actually had a little more of the bottle and now I'm curious to know what these are. All that is visible are the last 4 letters "rth's" and then an "E" or "F" from the word below. either way I think I'm in a good spot hopefully they aren't all broken ...super thin glass though.
