First off, this is a great forum...I've lurked around as a guest for months and learned a lot. I bought a house and this Kent Sherwood is in the basement. From what I've gathered online, this was a nice stove for its time and is still loved by many. The stove damper doesn't shut all the way and I found out why by looking up into the stove...the top/inside of the stove cracked and warped upward. In the photos you'll see the min and max position that that damper will move. Is this fixable by someone who knows what they are doing? Is it worth fixing?
