Antique gasoline blowtorch, Russel No. 37, brass For Sale

A antique gasoline blowtorch circa 1890, I believe it is a a Russel No. 37 and is listed as \" VERY RARE\". It has a one quart size brass fuel tank and a cast brass preheater cup and burner nozzel, wooden fuel valve knob and handle. The partial label on the bottom is mostly illegible. The fuel tank has a number of dents but I see no cracks, splits, holes or repairs, the fuel knob turns easily, this torch is untested. An unusual looking torch that will display well.
