I just called my Local NH Dealer - Timmer Imp in Aitkin MN.
Parts man there confirmed what you and others state that the horned plunger (C6NN3N729A) has been replaced by the standard plunger(LA33579B)
I told him the plain plungers would Not work.
He is going to contact NH and see what he can find out.
I sent him the photo below which he will forward to NH.
I guess it's a matter of hoping for the best but not expecting much.

Pictures of broken "horned" plunger. Does anyone know where I can find a good write up explaining how this steering valve functions. How the plungers, springs, ball are used inside the valve. Thanks for all the help.

I'm pretty sure if you get the big Ford (NH)manual - about $175 for the three sections it will explain how that PS block works with colored diagrams of oil flow, etc.
Over the years I've bid on about a dozen of them on Ebay but always got out bid so finally gave up.
I think you can also buy one on CD for not much $ but I never have - just like paper copies better.
