This is my favorite pump. My wife's uncle was selling his farm and he said he had a pump he wanted to sell. I knew he had a Wayne 70 and my wife talked about a visible pump that used to be on the farm. When we got there I made a deal for the 70. I asked about the visible so we went out to the scrap pile and I found a few parts for a Wayne 515. I was about to leave and he said he had one more pump in the scrap pile. We went out to another scrap pile and found this pump. A week later every piece of metal on the farm was scrapped. This pump is special because my wife's grand father used it when he first had this farm. Richard
