The only one I am familiar with is the one at Barnstaple Stoves and he wants $8500 and that is waaaayyy above my budget.http://www.barnstablestove.com/html/baseburners.htm
I do have a RC Garnet 48 that is in excellent condition but is apart right now as summer chores have overwhelmed me. Red Garnett 48
Sorry that is all I have right now. All I know is that this stove kept a 4000sq ft leaky old house in Rochester NY warm for many years. Attended by a 92 year old lady who refused to be connected to gas despite the screamings from her son who maintained it religiously and constantly worried about her freezing to death. Did she die of cold? no, she tripped over the cat (true). One point here is that is was a working stove until 2 winters ago. If yours is a barn find expect a lot of rebuilding costs that need to be budgeted for. What sized house are you heating and how big is the fire pot. I realized after I got mine that is it would be way too powerful for serious use in my application. That is OK as it was planned to be a collectible only and I doubt I will ever switch it on but do you need to consider that one?
They are made exceptionally well made stoves and I love mine. The Ensign does seem to be a lot fancier in design and if that is your taste then I wish you well. I would be interested to know if there are any differences in how they burn i.e. structural features that make yours a superior Anthracite burner. Are you planning to burn anthracite or bituminous? I'm sure these will burn both very well. Mine is a true baseburner with lots of mica windows and a hopper for extended burn time. If your stove is at Dougs (Barnstaple) he will explain all those features to you and what they do. If you managed to find one privately need help that is what this board is for. Send pics, we love pics and someone here will guide you through it as we have boatload of REAL experts. All these types of stoves really punch out the heat so they are still excellent investments even if they are expensive to buy.
