As per one question I had asked, ti does seem that there is info that it is assumed we know or that there is a tire reference book, as the sidewall measurement is missing. Is this just how it was, and it was all supposed to be looked up from reference material? Or am I missing something?

In this specific case, a 6.50-16 is a "Low Section Height" tire (88% Aspect Ratio). The key is the ".50" in the size. That's just the way they did things back then. Things are different now.
So as background, there are reference books. They are published by tire standardizing organizations. In the US, it's The Tire and Rim Association (TRA).
TRA publishes a yearbook every year that contains the latest information and some useful recent information, but deletes information that is too old to be much value - and that includes old sizing, like we are dealing with here. For that, you have to go back to those yearbooks that have that information - which means someone has to have an archive. When I was working, the company I worked for had such an archive - back to 1929. I hope they keep it going.
