Looking for a Barton-American UA 50 pump part. It is the top part of the pump, the early version that has the one chrome valve handle and 2 2.5 inch discharges. (Later models of this top part had 2 separate valves for the 2 discharges). The part is attached to the main body of the pump via 6 bolts, and comes off rather easily, and is easy to ship. I need the valve to move and operate freely. (I already have one that is rusted shut and inoperable). Please contact me at Email if you have the part for sale. I can send pictures of exactly what I am looking for.
