Just proceed with caution. That machine is definitely on route (or league I suppose) and this is the FIRST and only post by this newer user. I would ask for pictures of the underside of the play field with the same two games on either side in the background. Anyone could have taken those pics of that game on location. 
Most people with any experience at all selling games knows to remove the PF glass when taking pics for a pinball ad.
Another point I thought of is that any operators of Funhouse (and the other games in those pics) are going to know that Funhouse is worth spending a couple hours shopping the machine out before posting it for sale.
