I am satisfied with provenance. the collector died in the 1930s, and the goblet has her original paper hand written identification tag made in the period stated. I also have several other of her goblets, all of which are indeed 19th c, including a few which date to the period you give for these wares, which offers consistency in the composition of the collection.
although the condition is above average, there are 2 small punctures - and I do not mean ordinary chips - on the base which I thought were manufacturing artifacts, and a 3d small puncture or nip on the rim. otherwise the piece is pristine.
finally, there are no signatures, the application of which baccarat did not start until 1860, leaving baccarat still in the running.
given that the collector identified this as baccarat about 90 years ago or so, that its provenance seems assured, and that your information coincides with the goblet's nature, I don't see any reason to question its attribution as baccarat until something substantive disproves it.
thank you for the information.
