Shame there isn't a sizing reference for the MW pieces but thank you.
Are there lots of becher shapes on that MW page that match in shape and actual design (rather than just having one or other elements of the design) to those in the Launay Hautin catalogue pages then? And are there examples of PV or Molineaux Webb uranium glass from that period?
doesn't matter as it's just a piece of pressed glass, but you don't see many uranium pressed glass bechers that match a shape in an 1840s catalogue, so it's a fairly unusual piece. Therefore I'm loathe to give up the idea that it's from a maker whose design it actually matches and who was known to be making uranium glass items at that time, and to just say instead that it could be from anywhere
I first saw these designs a long while ago whilst I was searching for a maker for an overlay goblet (that turned out to be Saint-Louis) and thought some of the becher designs were lovely. But the few I found appeared to be in clear glass which is not what I was looking for. So this was a great surprise to spot suddenly on ebay and sold as a vase.
