Hello Jindrich - and my apologies for not thanking you for your reply on the 6th. I suppose that with the geographical proximity of Bavaria to Bohemia, ther wud be a similarity in factory styles. I wud imagine you have a very wide knowedge of this type of glassware. There does seem to be some range of ideas of manufacturer,
mind you I have nothing against a country which can produce Durer, Altdorfer, and Holbein.
Again my apologies for lateness in replying. Wud you recommend any particular book for this style of C19 decorative glass?? cheers Paul S.
