Welcome to the forum!! I suggest making sure that bin doesn't go to recycling quite yet. If that nice poison was in there, could be other good stuff. What else is in the bin???
Thanks for posting the link. I think I have found a new hobby. The little blue bottle is a pharmacy/apothecary bottle as well. Maybe for poison too? Maybe not?
The blue one, a handsome little fellow, looks like a "local druggist" bottle.. which can bring a pretty penny in the right local shop.. what does the embossing say??
What you have is labeled as a KV-1. Common as poison bottles go. Usual price for most are $5 - $10. They come in several variations with the POISON embossed one side, the other or both. A more scarce version comes in clear. The larger the size the more they command in price, but the largest only go for about $75. The one you have I'm guessing is about 3", the most common size.
