Let's Talk Ball Washers

And hoping somebody can help me out. Our Club superintendent gave me a Lesco ball washer and i really want to set it up in my basement , but i can't figure out how this thing mounts and can't find any pics online of either a post or wall mount. It doesn't mount like a Par Aide as those have a little female adapter on the back for the post. Lesco must not have made ball washers very long because there's not much info on them out there. i'd prefer to get the parts i need from a home improvement store so im not paying golf supply prices , but at this point im just hoping to learn how it mounts.
