old antique English ironstone china bowl, square fluted dish or baking pan

Beautiful old Alfred Meakin - Staffordshire England ironstone bowl, late 1800s vintage, marked with the Royal Arms. We'd guess this was used as a pie dish, as it's very foxed and spotted from use!
Size is about 8" x 8" across the rim of the bowl, and condition is good for the most part aside from the iron spots. It does show scratching and finish wear, and a small discolored crack or flaw at the rim as shown.
