The waterhouse top comes in two versions:

054-16B TOP WATERHOUSE-1968-1/79 NO OIL COOLER
054-16C TOP WATERHOUSE-8/76-1/79 W/OIL COOLER

So clearly Toyota made some rigs with an oil cooler and some without. I am guessing it was an option.

FWIW, This diagram shows the components that make up the oil cooler. And this page shows that there are two different oil filter assemblies (one for oil cooler equipped rigs and one for not).
The oil cooler was not an option on 78 model year. I do not think it came with one on FED spec non CA, non high altitude 40s. At least that is what the parts department at Desert Toyota told me.
