Most likely a DS Machine Stove Product. I'm starting to see a real beauty in a non electric dependent stove. If the lights go out,no sweat. Until the Harman Stoker becomes unsupportable I'm going to run with it. I will never send new stove money their way again. And,as a footnote,if I had need of a smaller stove for heating a small open floor plan,like a cabin or trailer,I'd bust a call to Larry T. and put the money into a refurb Chubby. Larry's no Corporate Bozo !
