Thanks for all your comments, I have learned a lot of interesting history while researching this. I think your absolutely right. I appreciate your friendly and knowledgeable forum.
I'm posting pictures of a flask that my friend found a while back. He said it was found under the floor of an abandoned house. Anyway I was hoping with a little bit of help to identify if it's authentic or not. I will attach pictures thanks for any help or insight. -cj
