For your consideration is this huge Mexican bird pin. I believe he is a cockatoo and has a turquoise eye. He is marked Silver Mexico. This is a documented before 1945 mark on Mexican sterling silver. He has tested and is guaranteed as sterling silver.
The pin is quite large measuring just a hair under 3 and 7/8 inches by 1 and 3/8 inches across the widest points. Weight is 30.8 grams.
He is in great condition with a wonderful patina. The pin back has a locking mechanism so I think it may have been replaced by a jeweler. I could be wrong but these earlier pieces normally have a thick C clasp. Fully functioning and secure.
