Have an old (1970's?) Jotul 118, green enamel. No issues with heat plates, no cracks. Haven't burned in probably 10 years. Lent it to a family member and when it was returned he had "taken it apart" to make easier to transport. Snapped off a couple of screws inside but unit went back together fine. Do these older stoves have any value? I could drill, tap and replace the screws, rope gaskets and clean up the stove. Can get pics, but it is under a pile-o-stuff in the garage. Any opinions, advice?
