Seems to be a rare stove in general, never been able to find much about them on google or anywhere for that matter. Since the company was sold they only bought the newer models so anything about the older ones like mine is gone. I have put alot of hard work into refurbing this unit and I am VERY happy with its performance so far, this is my first cat stove so I am getting used to the ins and outs, but so far I love the heat this thing puts out for being an older stove. I love the fact I can damper down the primary air on this stove and have it barely burning and still cruise at 450F on the stove top. I got lucky and found a Cat that would fit it on ebay, totally freak thing, I had bought the cat to convert my old Craft stove to a cat stove, then come to find out this stove is a cat stove and its the same size as the cat I bought, very lucky on that. Would love to hear some input/tips from other Sierra owners.
