Hello askhistorians!, it may be a long shot but I've been trying forever to find some comprehensive/dense books about Armor. ranging from about 600bce to 1400ce. Usually when I ask at book stores I end up following the clerk to the kids sections to eyewitness books "this is a knight. this is a sword." I'm looking for books that compare why the French did gauntlets one way but not like the Germans, a tome built like a bible.

edit: I figured I would ask about it here instead of r/books just because there is 432k people here interested in history, instead of the broad spectrum of all books.
