Hi, this bird was sold to me as Murano (Barbini Poli, though I took no notice of that). I just think he's lovely. He is 10.5cm (about 4.5 inches) high, sitting on a clear base. I think he may be in part uranium glass, cased in clear. His colour is orange fading to pale yellow in halogen light, and yellow/orange to green, in sunlight. (See pictures) His tail is solid, with a central rib. There is no signature or label. I've been to the Murano Zoo and I wonder if anyone could advise me on a possible maker. I'm guessing Livio Seguso as a possible, but your guess is better than mine. Thanks
