Hall rose pottery blue, unmarked ironstone casserole dish only, no lid

Unmarked Hall china casserole dish (no lid), 8 1/2" across the rim, 8" across the fitter. This blue is the royal wild rose pattern accent color, I think?

I can't remember is this is the officially named Superior China, or just Hall's oven proof kitchenware pottery, but it's heat proof ironstone in very good condition.
