This hinge, in the form of a goose, hails from the great collection of the late Prince Saud bin Muhammed Al Thani (1966 – 2014), who was regarded as one of the most discerning, knowledgeable and prolific collectors of his generation. He once said: 

"I buy masterpieces pieces from an important church, a major family, a great collection, these really interest me: they have a history and a provenance. You can get them in the best possible condition, and there are no problems of authenticity.”
