I have a Dawson Brothers coal burner insert that we removed for remodeling. It is in great condition and complete. Our house was built in 1895 and we feel this was original to the house. What is this worth and where could we sell it? I can get you pictures later if you need them. I also has a plate on the damper area that says "Vulcan Series No. 444 Grate" and on the rear it says "Genuine Chicago Gate."
