I found this 1 pint bottle at an old mining camp here in Ca. The camp dates back to the 1850's gold rush era, but, I realize this was dropped later....probably by a hunter. I can't seem to find any information about the Green Mill brand of Straight Kentucky Bourbon Whiskey. The label also says (I believe) Old Fashioned Sour Mash Whiskey, Distilled in Kentucky, Bottled by World Importers, San Francisco California. Any of you bottle experts know how old and/or anything else interesting about this bottle and company? Thanks.
