Wrenchguy,
Looks a lot like a pressure tank for a Coleman range, or maybe another manufacturer. I see the pump, I think on the end. What has me stumped is the "key" on top of the valve. They usually have a knob to turn on the gas. Note the places where it was mounted with two metal straps.
If you scroll down the page about 1/3 of the way down on this link , you will see one mounted on the right side of cabin stove.

The fittings also have to be in pretty good shape. How much value that is, I'm not sure.
I'd put it on ebay, list it as "Coleman? Cabin range pressure fuel tank 1930's?". That will more than likely bring the best money for it, if not more info from people with more knowledge about them.
