I was given a Better'N Ben's Stove/Fireplace insert. The previous owner was using it as a free standing wood stove and welded legs on the bottom of it. It has an electric fan which he never used because the stove was never in a fireplace. The rough dimensions are 25"W X 27"L X 23"H (height does not include the homemade legs). Does anybody know which model and year this is? Also, what is this worth?
