I have weights very similar, without that signature tho - which I'm pretty sure is a fake, apart from the glass itself being wrong for B the style, faceting etc points to Bohemian ca 1980's.
The earlier Bohemian weights
I have seen had much clearer glass and the faceting was very good,
with smaller facets, the newer ones seem to have bigger and fewer facets.
The borehole alone should sink any thought of Baccarat no?
I bought 5 similar weights on an auction for about 120 USD including buyers fee which i now feel was a bit too much.
