I acquired this stove literally of the floor of an old barn. It is in very good condition. No cracks, seams all tight, all parts are there. Some surface rust. Cast into the cast iron is BP Learned & Co, Patented 1850. Albany New York, NY. It measures 20" high, 14" wide, 23" deep. Is it rare, have value? I want to take a wire brush to it and then paint it with black, flat heat paint. Any thoughts?
