Hi flying free,
Not really, although i did see one a few months ago on an Australian retail site that I'd followed a link to whilst seeking out some info on a Loetz piece. I remember seeing it was listed purely as Murano and had an asking price of something like 350 Australian Dollers which had me staring in disbelief at the time. When i checked other prices on the site I realised that the sellers prices were really on the optomistic side to say the least.
However i still have the vase on display and i still like it. Yours sounds like a nice one two the green and amber would give a nice contrast.
Sorry I can't help you any further with it.
