Thanks for the info. I may need to do that.
The Back plate just says reg. Keystone MFg.# 1073 It actually looks like the one that europachris has posted with his signature, but the glass has been replaced, (by Keystoker) with sheet metal. (The glass broke in the original and we were tired of trying to keep the glass clean, so we replaced it with the metal. I actually live about 20 minutes for the Keystoker plant.)
My husband was the Keystoker expert. He cared for both stoves and they did a great job heating our old and drafty house. He used to have the literature for the stove, but he passed away in 2004, and I can't seem to locate it.
