Wow! Sorry I can't help you but VERY cool poison. I prefer mine to have the words Poison, Poisonous, or Not To Be Taken. And I loathe amber but will tolerate it for the right wording. Like the three embalming fluid bottles I have. Primo stuff.
I bought the bottle shown below in 2002 in Arizona to put cactus quills in. I added the modern cork. It has a seam which leads me to believe it's either decorative, or a reproduction poison (due to the ridges). Of course I'm hoping it's a real poison but even to my newbie, untrained eye, it...
