Vintage portable furnace, stove for sale. Don't know much about this so please rely on photos. I believe this is quite rare make and model. At least I've never seen other one like this before. Label on the tank reads " the portable furnace and Patents co, Patent. Carrington Nottingham. Size no 2" In original as found condition. I only cleaned loose rust a little bit. Open/close valve isn't frozen. It moves fine as well as pump and tank filling cap. Top of the tank made of copper, bottom ring of brass and tank bottom of steel. Have lot of rust and corrosion on it. Tank still contains fuel which will be emptied before posting. Please study attached photos for more condition details.
