This warming dish has the famous European blue onion designed plate with a silver plated brass bottom. This piece is an early one with a hand painted blue onion pattern. There is only a marking "J" on the bottom of the silver dish.  It measures ~ 11 1/2" from handle to handle, 9 1/2" dish diameter and height is 2". The warming dish comes with the top and chain.

The chain for top is not attached to the dish. The plate has many crazings on the body consistent with its age. The metal body has one small dent and the top is also dented but screws on tightly. Some silver coating is worn at the top and bottom rings showing the brass base. Please see last photos for detail. Overall it is in good condition for its age.
