I don't know the full story, but it was found in Eastern WA, but not in the Walla Walla area, we don't want to give up all our trade secrets. A friend was doing business with a neighbor and saw the pump sitting out next to the shed. Spence contact the owner and made an offer. A month later the farmer contact him and the rest is history. He paid a lot of money for the pump but it is still a bargain considering what the pump is worth. This is one pump that I believe will continue to increase in value. There is still stuff out there but the days of bargain prices for the most parts are gone. Richard
