Anyone know anything about thsi company? Have a Model Two wood stove manufactured in 1980 that appears to be in good shape, no visible cracks, etc... https://www.hearth.com/econtent/index.php/wiki/7516dd5ec5067306a972a6a5c9648524/ Any reason I would not want to use it in my fireplace? Would be set in fireplace attached to an brick outside chimney with a clay lined flue...do you think I should run a standard stainless steel liner or an instulated one or dont worry about either? Stove would be used a backup heat. Thanks!
