Hello, New here and just purchase my first pump to restore. I am having difficulty with what exactly I have. It is rough and missing pieces. I believe it is a Fry may west 117 but not sure. All the pictures I see have the handle and the pump in the base. The one I have has the pump on the outside of the back. Any help would be appreciated.
