Chinese Warming Tureen

Hi Peter,
I purchased this blue and white Chinese three piece tureen many years ago. It has a Foo dog on the lid and lion mask supports for the metal handles. I presume that it could be 19th century but it does appear to be an unusual Chinese dish having a middle that lifts out presumably to have hot water in the bottom to keep food warm. I would appreciate your opinion and any comments you can give me.
Best Regards
Paula
