Old Kerosene? "PERFECTION 320" 2 Burner Stove

"PERFECTION 320", "MADE IN U.S.A.", and that's about all I know. It's a 2 burner stove that appears to me to run on kerosene but I've been wrong once or twice before. I just noticed that the tank has a Delta symbol (pyramid) and it reads "TRADE MARK" above and "REG. US. PAT.OFF" below. Most of what appears to be the original black paint is still present. I don't know if the white paint is original; kinda' doubt it. I don't even know if all the parts are present. It looks as though it would fire right up with some fuel. From an estate sale. +/- 24"l x 13"w x 16"h. As-found.
