antique china game bird grouse plate, shabby stained crazing 1800s vintage Petrus Ragout pottery

I love the colors (and the wear and the staining!) on this lovely very old Petrus Ragout Maastricht Holland plate. The bird at the center is a grouse, I think?

Plate measures about 9 1/2" in diameter. The staining and crazing is very noticeable, part of it's charm. There's a couple of short hairlines at the rim, very tight, no serious cracks.
