There appears to be information here on the Pressglas Korrespondenz about having found original lithographs (?) or something for the Launay Hautin catalogues .
https://www.pressglas-korrespondenz.de/aktuelles/pdf/pk-2001-05-musterbuch-launay-hautin-1840.pdf I'm not sure exactly what it says as translating such a huge body of text loses me.
It seems to me the Launay Hautin catalogues appear to have been drawn with architectural precision.
On page 10 of 39 on my link above it shows a green goblet and the matching design. I think it says the design boards were in life size and actually the green goblet appears to be a direct match for the design.
What I have is a tumbler that appears to match the shape in the LH catalogue.
But it definitely does not match the shape in the PV or MW catalogue at all.
So are you saying the PV and MW catalogues could be drawings of drawings and therefore not accurate, which might account for any difference in shape therefore indicating that on that basis mine still could be by PV or MW?
And did you mean 'Unless you find your glass in a Baccarat (
catalogue pattern book), I doubt you will pin it down '?
Because I think the LH catalogues were pretty specifically drawn from what can be seen on the PGK link. LH were chosen as the agents for initially a joint Baccarat/Saint-Louis sales outlet initiative in Paris - and then subsequently Bercy and Choisy-Le-Roi joined the consortium as far as I have been able to make out.
I take on board your points, but since the beaker doesn't match the PV or MW shapes but does match the LH catalogue design, I'm less dubious than I might have been had it been a match in shape for all three if you see what I mean.
I can see that PGK has done some other comparisons to the LH pattern book drawings of items produced by other makers (see page 9 of 39 specifically the Sandwich goblet and the possibly Rejmyre/Kosta footed bowl), but to my eye they don't even look remotely similar so I can't see why there would have been any confusion in the first place - bit confusing really but I might be misunderstanding the reason why they showed the comparison.
Anne, that's a great find. The shape is very different to mine and the glass quality appears to be extremely poor by comparison to mine as well. Interesting. I'll do some more digging.
