In any case, "par" as we know it today wasn't primarily used until the 1st decade of the century.
Before then, the term "bogey" would have been used. Bogey isn't quite the same thing as par as the standard is a bit more relaxed. OR, just describing holes as short holes, two shotters etc. would have been used. The term "par" comes of age at nearly the precise time the Haskell ball hit the market and became the ball of the future. With the intoduction of the Haskell came the more stringent standard of "par".
So to answer your question, I am not convinced the idea of a driveable par 4 existed before the construction of Huntercombe and Sunningdale IMO is the early stages of the Golden Age.

We can agree the concept of par may not be relevant, but does that matter in terms of the concept or design of the hole. Surely the concept of a hole that could be reached in one with only your most heroic or foolish shot using your longest club that offered strategic alternatives to the less brave or skilled player would have existed.
