Antique miniature Kate Greenaway-type dishes--ID?

This set is not dollhouse size, but it is miniature--the larger of the two tureens is 8" across
(i ncluding handles), and the smallest set of four plates measures 4 3/4".

They are old--they show lots of crazing, some brown marks, and what I can only describe as tiny, tiny bubbles in the glaze. Two pieces have very faded blue markings on the bottom, but I can't read them. There are 21 pieces in total.

Any thoughts on the possible age or maker?

TIA

Early 19th Staffordshire made by the look of them.

 

Thank you--is there any way I can research it further? I've looked and looked on the internet.
