It is a long time since I visited the Baccarat museum, but my gut feeling is that this is not Baccarat.
Unfortunately, I cannot tell you what it is! This is one of the most annoying thing about glass identification - it is much easier to say what something is not, than actually to say what it is!
Someone will probably recognise it, and apologies both to you and the Baccarat experts if I'm wrong.
