Thanks for bumping this Anne, clearly some revisions to be made.....
David Encill's initial two green vases (p1) are from the Rosice factory, but not Schrotter, pattern number 974.
David's second pair of images, the blue wavy vase is again Rosice, pattern number 1272, but definitely not by Frantisek Vizner, as confirmed by the artist himself, therefore designer unknown.
Adam's (David555) pair of images from the same page, the left hand vase, is Sklo Union but pattern number unknown, and tho' I think I know who designed it, and which factory made it, I am not prepared to comment until confirmed. The right hand vase, still remains unidentified, and even with the massive increase in information in the Sklo Union database, (now at almost 3,000 items) I am still of the opinion that this may be Polish or Scandinavian.
