I have no knowledge on this subject. However, my grandfather left me a Fisher Fireplace insert. I don't see a model number on it. It is roughly 34x18 inches in size. It is double cast iron door. How can I find an estimated value on this item? Can someone give me a rough estimate? Thank you for your time
