I would describe your glass as .....
"wheel cut" crystal stemware ....... and therein is the "
problem" ....... because the decorator(s) cutting the "pattern", more often than not, did not work for the company that produced the glass.
This person said it better than I could ...... in response to a similar query, to wit:
Your stems were gray/wheel cut so even if the manufacturer of the glass could be determined, it most likely won't help with who decorated the glass or a pattern name even if there was one. Gray/wheel cut patterns are almost impossible to ID.
Manufacturers did do this type of decoration and except for the ones they did most didn't have names. They were easily copied by the different decorating firms, of which there were many both large and small. There hasn't been sufficient demand by the collecting community combined with the lack of uniqueness of design to entice anyone into taking the effort to document the designs, and who did them, ........

I've met a couple gals that could "cut" about any pattern or design you wanted cut on a piece of glass. They worked for one of those "decorating firms" and that's all they did all day long.
And ps, that most probably explains why you have one (1) piece of "marked"
AH glass in your collection.
