I'm fairly new here but have been lurking for a while. I live in the mountains in Gunma, Japan and rely on a Napoleon 1400 for primary heat in our home. We have a cabin in the mountains of Nagano and I'm in the process of installing a Jotul F500 there since our newly wed son and his wife will be wintering there. The F500 is actually replacing another stove we used previously and that is the one I'm trying to identify, since I'm hoping to find a new home for it. I was told it was German in origin but cannot find any markings on it whatsoever. It has screen doors in the front and a baffle in the 7 inch rear chimney flue. I'm attaching a photo as well.
