Argyle King
Legend
At least according to the DMG, he got a lot of the armor descriptions out of this book, Armour & Weapons by Charles John Ffoulkes

Or in other words, studded leather.
Also ring mail is described, as is banded mail.
Did these armors actually exist? Perhaps not, but pictures depicting such armors did, or so people thought.
I'm in no way an expert on the topic, but I've dabbled in weapon and armor lore a bit. To the best of my knowledge...
Banded Mail existed. Though, the manner of making it caused the underlying mail to be less flexible. As a result, it was not often used to cover areas of the body which needed to be able to move a lot.
Ring Mail existed, but was mostly used outside of Europe.
Studded Leather that actually worked would be closest to being Brigandine. A lot of sketches and pictures show people wearing something that looks like Brigandine, but what it actually is is just a rivet pattern put onto leather (or cloth) because it looked fancy/fashionable. This started with actual brigandine studs being made into patterns, and the idea was then copied in civilian fashion. D&D's "studded leather" is something that I believe has roots in what would more accurately be called faux brigandine.
