Redwing, National, Roseville? Crock Bowl Indian Chief

We are selling a crock bowl and are unsure of the maker. The bottom has an Indian Chief head and it says national next to it but I'm not sure if that is the maker. I have not heard of them before. It has a wire handle. The bowl appears to be very old and has a hairline crack that is 2 1/2" long on the bottom and goes up the side. This is a very small hairline and should hurt anything. This bowl measures 10 1/4" wide and is 5 3/8" tall. Other than the mentioned hairline t are no other cracks or chips. If you have any questions please email us. Thank you for looking.
