antique English ironstone bowl, deep dish w/ pie crust edge, rustic vintage white china

I love the unusual pie crust crimped edge on this old white ironstone bowl! It's marked Johnson Bros - Royal Ironstone China with the English Royal Arms mark.

It's about 9 1/4" overall diameter x 3 1/4" tall. Condition is not perfect, this has surface wear, scratching and staining. No chips or cracks.
