Thanks so much for your information and photo of the Tag. Thank you everyone else for everything contributed to this post. Going by all of the information I could research here and elsewhere, I was able to have a reproduction tag made that, to the best of my understanding, is at least 98% authentic in details of appearance and content.
Some things just cannot be done on your own.
This forum has been one of the greatest sources of information, I believe a source of information that cannot be found anywhere else in the world. Much gratitude!
