I'm not overly secure on this, but I do think there is a good chance it could be Hungarian glass not Bohemian.
The only places I know the names of and nothing about are Parád and is it maybe Zlatno (?)
I cannot find a match on the opaline glass, but the shape is good for similarities. There is something curious about the stems and feet of Hungarian glass, or rather, not curious, hard to explain, but they just 'look' different to Bohemian glass bechers and stems/feet somehow. Slightly curvier, thicker, clunkier. Slightly more rustic looking by comparison, both in terms of decor and style.
Wish someone on here with more knowledge in this area would pop up. It's a country of glass that is not well known and publicised really - well I mean especially 19th and earlier centuries.
I have some resources but nothing in there matches yours except to say I think it could be by the shape of it.
I wouldn't move it to Bohemian just yet.
Ooh, there is more info here on the Prisma Gallery site but I guess you might have found this:
