porcelain plate

This little plate/bowl is painted with yellow base, black circles and squares and flowers in burgundy green and it is finely trimmed in gold around each flower, but some has worn off.

I think this is porcelain, it makes a high pitched swishing when you rub your finger around the rim. The maker mark I think can identify it if anyone has ever seen it before. Pretty distinctive blue mark on the underside-- it looks like a thimble with two lines through it. The plate has a slightly raised rim on the inside and the paint has worn off that part, but on the underside you can feel nothing- not indentation though it's a thin plate.

Thanks for any help in advance!!
