Hello and welcome.
I can't tell what the rim of the glass really looks like. Is it thicker than the rest of the glass?
Has it been heated to make it smooth, and can it be seen if that heat was applied by machine or by hand?
Or is it a tiny bit turned over?
A close up of the rim might help.
The domed foot is a bit unusual for a machine made glass, I have some pretty uranium glasses with air-features in the stems, with domed feet myself and we suspect they are German, they're not good enough to be St. Louis.
I don't actually know which companies used this feature.
Have you tried trawling replacements.com ?
(Make sure you have a nice cuppa and some biccies, you'll be a long time.
)
There are other people here who might know a lot more than I do. Hopefully, they'll say something too.
