I have this stove in my garage it was my paps just trying to find out more info on it. I saw a picture of the full unit online and they refer to them as a octopus furnace. Mines naked and still in decent shape. What time frame are these furnaces from. How much do you think I could sell it for I was thinking of just selling it for what I'd get at the scrap yard but not sure. It's in the garage taking up space don't plan on using it since garage is not insulated.
