I can't tell what the brand is.

Is it an EPA certified stove? By that I mean is does it have a catalytic converter or a secondary burn chamber?

If not, I wouldn't buy it. The older stoves are considered "smoke dragons" and are not very environmentally friendly.

My nxt door neighbor has an "Fisher" woodstove, and they were considered the Cadillac of stoves back in the 80s. Today if she were to replace it, it would have little more than scrap value.
