Broken Stone was suggested when I first began the Quest for the Broken Stove. It and Broken Stove Eye [what in the world is a stove eye and how does one break it?] may be the only patterns that we can turn up. I am not giving up just yet, though the trail is getting faint.
I downloaded the Broken Stone photo you posted. Thanks for taking the time to add to my "body of knowledge" about Broken Stove. You never know about the parentage of some quilts--perhaps Broken Stone inspired some old quilter way back when, and she named her version Broken Stove.
