Well Head?

I found this in a foreclosed home. It appears to be a well head with the part of the pump still mounted on it. It was in a space that was the size of a well pit. They may have built the house around it and used three of the walls for the house. Any ideas? I was not able to find anything just like it on the internet. Ken



How big was the pipe?

The pipe from the floor is about 6" dia.
