Thanks for the link to Antiques Atlas. I believe my ceiling light is an original antique and not a later reproduction. It has the patina of considerable age. The form of construction is not how it's done in recent times. The link used to unite the three parts of the suspension chain is brass, obviously old, and complicated in design. The chain itself is of quality construction. There is a small piece of wood missing on the framework that has gone completely brown. In other words it's an old breakage. The seller on Antiques Atlas was convinced that his ceiling light dated to c.1920. A local antiques dealer thought 1910-1920.
