You would think that the seller would list a bit more info,and pictures, for that unit. At least a year of manufacture. Tom built some late model hydro cats,and I suspect this could be one of them.but the add really does not say? It would have been close to that price new if it was a hydro cat. He did do a nice job on the cats they built. But once again we just don’t know without the add at least listing a year.
