I don't know squat about wood stoves, we've had the same one for 25 years or so. However when I got ours I just had my heart set on one by Vermont Castings. That was a long time ago. I understand the company had difficulty and they turned out some bad product. So it goes. So my son calls me and says a friend of his is there and his dad had an old one for sale. Here is all I know about it, the thing is rusty, its the "Defiant" model. It has solid cast iron doors, no windows, they tell me it has no cracks in it at all. I asked the boy if it was 'catalitic' or not because I have heard that matters. He looked at me like I had asked the meaning of life. I had to admit I didn't know what it meant either, but I had to ask. I can go take a look at this thing next week if I want to. I don't even know what to look for other than if its straight, in one piece (he says there's a handel broken off). What's a catalitic converter look like in a stove? Are there any internal parts I should be taking a good look at? Oh, he want's $200 for the thing but I got the firm impression that could change. Tell me what I need to know.
