The armor at 6:10 the 'plate thing' is a suit of Brigandine. Which is literally plate armor consisting of many interlocking layered plates, covered by a layer of leather or satin. It's pretty much as hardcore of a suit of armor as the more knightly plate armors.
As far as i know, 'studded leather' is literally a modern misinterpretation of Brigandine as from the outside it basically looked like leather with studs in it (it's just that those studs were bolted to metal plates.)
Nice unbagging. Seeing a few of them build and paintwd up qould be nice. Maybe even compared to other manufacturers for scale. Looking forward to follow your channel.
"studded leather" never existed. "Studs" on armor are rivets to hold different stuff together. Like in brigandine armor, which is usually overlapping metal plaquettes riveted to the underside of a suede or heavy fabric outer layer (it is from seeing this that Gary Gygax got the misconception of studded leather from; he didn't know jack shit about armor).
