This may be too basic for you---I'm not sure how far along you are in your research. If so, let me know and we can work from there!
Becco di oca (goose beak) has been a popular shape amongst Italian glassblowers and dates at least back to the Etruscans, who made vessels with elongated "beaked" neck and lip, such as the one(dated 700/675 B.C.) which I have attached---it is from Erika Simon's catalog of Greek and Etruscan antiquities at the Kurashiki Ninagawa Museum.
Dante Marioni uses this shape in his Chartreuse Pair, which you can see pictured on our website: http://www.cmog.org/audio/chartreuse-pair
I am sending some bibliographies on ancient glass, which may be helpful to you in your research; however, you should also look at materials on Etruscan pottery, if you are interested in the shape more than the material. You can search in our online catalog (rakow.cmog.org), as we have a number of catalogs of ancient ceramics.
