Does anyone know what this would be valued at or at least where I could find more information? It's an antique wooden keg (with brass fittings) that will hold about a gallon. It is set up to be pressurized, so you prime it with a little pump handle that is on the front (spigot side) of the keg. the bung is set up with a brass cap with a rubber top on it. When it is pressurized correctly the rubber is supposed to pop up. It actually has a cardboard card on the back of it that describes what it is and that it is made by the Coleman Company. I've looked everywhere to try and find out more information on this piece, but am out of gas. If anyone has a clue, let me know. I can post pix if needed, but just didn't have it with me (in storage). Thanks for any help in advance.
