The style of your bird looks like AVeM to me, but I don't know. AVeM made many birds that had the front of the crest that went down in a ridge to the bill like yours does. The shape of the body also reminds me of AVeM. I had a dog that they made that had the vanilla alabastro accents. AVeM would be my first guess for your bird, but with seeing one with a label, I don't know.
The "Seguso" bird in the link doesn't look like Seguso or Archimede Seguso to me. Some people call anything that has alabastro-like glass Seguso.
I like the tail of your bird. It is a good looking bird. If it is AVeM, it is one of the best that I've seen by them.
