I'm curious about this identification as the linked one on CW being from the 'Floret' range at Harrach.
The one I've found in the Passau book band IV Das Bohmische Glas is opalescent with a slight yellowy tinge as far as I can see and has a flower pattern on it and a crimped rim - it looks like a Walsh Walsh opalescent vase. There is quite a difference in the design of them, although they are both opalescent glass with a pattern on.
I wonder was all the opalescent range called Floret? It's just that 'Floret' seems to imply 'floral' and the 'maze' design vases don't look very floral. I don't have the Harrach book only the Passau with the floral vase in it.
