Well, one of the operative words in the question is "ranch". I think it would be safe to assume that he butchered his own stock, most ranchers do, or did. This means he had a good supply of lard.
Add some beeswax, either store-bought or from his own hives and there are two big ingediiants right there. Fact is, a body could do just fine with only those ingreiiants.
To make things even better add a third, some kind of liquid vegetable oil, I've fooled with olive oil but it seems that the cheapest pure veg oil on the supermarket shelf is just as good as the most expensive olive oil.
Here is my super-secret formula, please kill yourself after reading...
About fifty percent, more or less of beeswax, the rest lard. That is a high summer recipe. As the weather cools add some veg oil until it is as soft as you like.
All these are available on a ranch.
Further research prooved that vegetable shortning works just about as well as lard.
It ain't 'zactly rocket surgery nor brain science. There's lots of slippery stuff that works, much is found on a ranch. Garbe and Venturino made money do to skillful marketing, their goo ain't any better than Dick's or mine or Be-A-Triss' Dad's lye soap.
What counts far more than the formula is that there is enough of whatever one uses.
