The tray is about 15 inches in diameter rimed in sterling silver and marked Jos. Heinrichs, Paris + New York, Sterling Silver, Pure Copper.

The chafing dish set stands about 11 inches to the top of the lid and includes a hammer copper water reservoir with a hammer copper serving dish and lid on top. No monogram.  Included is the hammer copper burner which is also marked.  Circa 1907 until the First World War when Heinrichs closed the shop in Paris.  I believe the rabbits are solid brass.

Heinrichs started his business in New York in 1897. His work was retailed by luxury stores, including Shreve, Crump & Low, Tiffany & Co, and others.
