Brian, back in the 50's I can remember going to the local store near the area where I live and passing by a lot of oil field pumping jacks and there was this little one only about three feet tall, as the years passed I stopped where the pump was and it was pumping fresh water into a tanks and there were lines going to houses in the area, a wooden tank, rusty lines but that is all the water they had, I thought they were really up town we were still using the shallow well with the hand pump on it, when I pass though that area again I will take a picture of that little pump, one of the small oil companies has it at there place by the road, thanks for all the work you did on this project, Lathe Nut
