Thats your basic "Hot Blast" design stove. pick your brand, they all made one just like the other. basically a big box to burn wood in, and they will burn a ton of it. they were inefficient burners but they do heat well if you can keep them fed.
They are a well built stove that should give years of service. From what I have been able to research they were made by a small company owned by a lone owner. When he retired he closed up shop end of story. That is pretty much all I was ever able to find anyway.
