from what I understood from reading on the site was that the sticker was widely used on any of a number of glass works
The Bohemia Glass labels are easy to get confused, but the gold coloured(now blue, and stating Czech Republic) Bohemia Glass or Bohemia Crystal "Made in Czechoslovakia" are Glassexport/Skloexport labels (registered in the 1950's and 1963 respectively) and not directly connected in any way to labels for Sklarny Bohemia, or any other glass-works. In fact you can often see both factory and Glassexport labels on the same piece of glass.
See this example of double labelling from Sklarny Inwald/Sklo Union Rudolfova Hut' with the Glassexport label: http://glassgallery.yobunny.org.uk/displayimage.php?album=33&pos=5
The label as shown on the black/white vase would have been used for any of the factories within the Sklarny Podebrady group at that time. That also included a couple of semi-autonomous decorating shops linked to Zavod 2, Nizbor works, once Ruckl's and now, once more Ruckl.
Once re-privatised Ruckl resumed the use of its historic Stork label.
