I'm just guessing, but does TPHP=Thompson Power Hydraulic Products?
Thompson and Pesco made the original hydraulic pumps for 300-450 tractors. C/R is Chicago Rawhide, a seal manufacturer, and is still in business. See if they offer a cross to the old seal.

I've run across some bearings that the bearing manufacturer will only supply to CIH and aren't crossable to anything else without serious modification.
