'... it seems like the teardrops in the Baccarat drawing are shaped differently. It looks like they are longer, and the horseshoes on the bottom look a little different, too.'
Having said that it's difficult to replicate in a drawing, which bits are the raised surfaces therefore looking narrower and reflecting the light and then also the bits that are the bevelled edges of the raised teardrops if you see what I mean. I'm sure you do.
Even despite that though, I don't think it's an exact match because of the height of the 'ridge' where the bottom bit with horseshoe design starts. Mine starts slightly higher up the becher than the Launay Hautin drawing.
So it's possibly in query anyway it being Baccarat.
With regards the age. I am pretty sure that whilst designs were repeated, there were 'fashions' for these things. Perhaps not as short as a year of course, but definitely a 'period'. Even with Bohemian bechers, the underside base changed over a decade and the shape changed - subliminally in some instances but it did. It's difficult because Bohemian bechers (in that type of style i.e biedermeier - not necessarily that design) have been produced from early 1800s up to now. But generally you can make a good guess as to era or thereabouts because of certain aspects of the glass. More difficult with a pressed/mold blown piece with no decorative features or anything on the base. Although of course, there will always be something that was reproduced in a style or similar with no defining features that help identify it as a much later period, which can stymie the id.
I think this is 1840s and may be up to 1850s but it certainly fits the 1840s. The base is the same as those on the Launay Hautin depictions as well. In fact the design reminds me most of Lithyalin/Steinglas/hyalith bechers and the one I've seen in a similar tulip shape as well as the ones I've seen with raised 'lenses' all appear around the 1835 mark:
Examples could probably be found for any era of course, but generally that is the era they date to:-

I've not time to try and find more that have similar designs but there are plenty.
I'm curious about why it has that particular odd glass mark on the inside of the indented base.

I will keep looking. I'm sure it's not MW or PV. And I'll just keep Baccarat on the back burner for now.
