Thank you for the friendly welcome Paul.
I have done some research on the name (headache!). The best I can come up with for a translation is "Ynufehe" in Fraktur script. The hard part is the fist letter. "V" is more common leading "n" but it better matches "Y" because of the left swing of the tail at the bottom or was that just flare?. But if you start looking at Fraktur, there are some examples that would make you think, maybe!!! lol. The "f" could also be an "s", but I believe "f" and the "h" could be an "n" but better resembles the "h".
I have tried searching the name with all the variations of letters but have not found anything. When I started getting German web sites, I knew I was getting close but no exact match.
The script dates 1500s - 1940s. But the degree of wear on the base from being moved around is more than the past 100 years. All the engraving is carved and not etched.
I have not checked it with a black light. Gave those up in the early 80s,

so I may need to pick one up to verify the glass type.
I'm still searching but looking forward to any other information anyone may have.
