The valve shown in the picture is called (in common IH terms) a Christmas tree valve. It is a OEM style 2 way pressure open center valve. The original installation connected the return pipe as it is in the picture. The supply pipe was from the Elbow shown half way down the side and behind the Liftall pump control lever (now locked in the on position with the rusty strut) if the input to the Christmas tree is from the other side of the tractor, and is attached to the front most elbow on that side, it is a non-live Liftall, Belly pump, and, as Delta indicates, it does not lift when the clutch pedal is pushed in. If the hose goes to the front of the engine, and a external hydraulic pump is bracketed near the governor, and belt driven from the crank, then it does have live hydraulics, and is using the belly pump for a reservoir. In either case, the dumping of return oil from the open center design splashes oil into the filler neck pretty radically. To "fix" it so that does not happen, the valve is going to need to be mounted with new brackets and held in place to allow the re-routing of the return to the bottom drain (with a T and closed nipple) so it does not splash.
