When I said 'one of these sets' in the post above the link doesn't appear to work although I thought I did a image url to the link - so mine is like the second set down on this posthttp://www.glassmessages.com/index.php/topic,56023.msg336832.html#msg336832
and then there is this which I've just found
It was formerly in the collection of the Musee du Verre and now in the Grand Curtius. Identified as 'Verrerie Nizet, Liège, debut 18e siècle'
It isn't the same 'knit' or design as mine or the one posted earlier in the thread though https://commons.wikimedia.org/wiki/File:Corbeille_et_plateau_(Verrerie_Nizet,_Li%C3%A8ge,_debut_18e_si%C3%A8cle),_Grand_Curtius,_Li%C3%A8ge.JPG
I suppose I'm now wondering if mine might be early 18th from Nizet given it is not lead glass, or middle 18th before 1762 from Zoude, or did both Nizet and Zoude make lead and non lead at the same time?
Also, the plates I've managed to find identified as 'Liege' all have the pinched knit as the outer rim of the plate, whereas mine has a plain rim to finish off the knit as it were, in the same way as the bowl and the same the plate in the Felice Mehlman book I think. I wonder if that denotes a different time period or a different maker?
