fancy china - is it anything special?

UPDATE -- this whole set of china has found a good new home where it will continue to be loved!! :-) :-) :-) :-) :-)

AND THAT brings me to adding two new pics just now, of one particular piece. It is a medium sized (?) serving dish with lid, plus a little perforated part that sits inside the bowl.

HELP -- DOES ANYBODY KNOW WHAT IT IS FOR??? (I told y'all I don't know nutthin' about fancy china??!!)

--------------previous description below---------------

*NOT* looking for any monetary valuation -- just ID, general info, and/or opinions about what I might to do with a cabinet-ful of this china. I don't have any use for it (or space/time to pack and store it well) and think I understand that such things are far out of fashion nowadays, apparently with negligible demand or interest (value) from most folks -- unless accidentally something really rare or unusual, which I presume this isn't.

(and in case it needs said, I know next to nothing about such things...)

Pictured is one small plate to show its (pretty!) pattern, and the maker's mark on the back.

WHAT SAY YE, fellow friends and Collectors?? If I don't simply pretend I never opened that cabinet to find it all, (difficult, plus there's other stuff in there I *do* want) I might know someone that would take it, or Goodwill takes most everything you haul to them, or ???
