Great site, love the old stoves. My stove is solid with no cracking or rot, I just would have a hard time burning it in my house. I did fire it in the back yard just for fun when I brought it home. I used a 6 foot stack and about 30 lbs of nut coal, amazingly enough it wasnt that hard to control the burn, I got about 7 hours out of it ( not so good). I got 375 deg on the side of the stove and 650 plus gas temp(not very eff.). The stove is fairly tight but not air tight, I would fear having a runaway stove.
