Cox Whitman & Cox Stove

Hi all, I am trying to get some info on an old coal stove for a friend of mine. It was his dads stove and my friend got it when his dad passed away fifteen years ago. The stove is a pot belly looking stove. It says Cox Whitman & Cox on the front bottom of the stove. It also says Philladelphia, the model is Artic 9. Thanks for any info.
