  Mini cast iron stove. 
This is a "salesman's sample" miniature cast iron stove.  Salesmen would carry a (heavy) suitcase of these around to show the housewives the latest models of wood stove. 
I have a feeling this one might be a relatively modern reproduction, because the pans are labeled "TAIWAN" on the bottom.  I'm no expert, but I doubt that such an item would have been made in Taiwan in the 1800s.  Of course I could care less whether it's old or new: Either way it's a really neat little mini-stove, and it's definitely cast iron.
