Hi Sam.....If her story is true, and the skillet doesn't really mean that much to you, it might be a good idea if you let her or her husband have/buy it. If you could establish some kind of repore with her husband, he might be a useful link to information and knowledge about the Martin foundry and the products they made. He might even have access to some of their old catalogs. It might just be a good trade off.
