Im sure they arernt worth a thing. Ill send you a check for shipping

They are probably taking up room in your shop right? hehehe, just kidding. I know Parker had barrels left over, and have seen a few for sale but dont recall how much they asked or got. Are they steel? Are you able to post any pictures? If you dont have any luck here, try posting over at the parker board.
