Nice birds and definitely Cordonato Oro. I like the clean, confident lines, which says to me that they were made by a good company. I had a look through Anita's birds and nothing there like them in general style. You can't say Cordonato Oro therefore Barovier & Toso, because, as Marina Barovier wrote, the style was "widely imitated."
I'll be interested to hear Anita's or Tami's opinion.
