Great parrot! The label was used from the early 1960s until the late 1970s according to Marc Heiremans in his book Murano Glass: Themes and Variations. The etched numbers are probably the stock and model number. That is what they look like to me. I would love to put your parrot in the Murano Zoo. If you would like to put it in the zoo, just send me a picture -- the first one will do -- the height and your full name and I'll be glad to find include it. You can reach my email by clicking the envelope on the left.
If you haven't seen the zoo, the link is under my signature. Your parrot would be a great addition.
