15th century ranges a lot depending on early middle or late and where you are located. early 14th were more basenets and kettle helms. late were sallets etc.
that is really early for real "plate". topof helmets, really there just head coverings with face masks. then come the knees say 1240s/50s with better helmets that cover everything. then the shins get covered etc.
Slightly related, actually because I need people who know uniforms of WW1
Anyone can identify which part of this trooper gear comes from where, for example the helmet looks German with a French... crest? thing? on the top of it
helmet is sudo german.
overcoat looks like french with russian influence but german colors
ammo pouches look like Austrian
shovel looks like a leather covered ww2 american
pants, boots and puttees could be german or anyone for that matter, can't see the bottoms to tell.
pack sorta looks like german influence
i know of no such animal in period. a lot think it is just the hauberk with a front and back split. itf it was tied around the legs you could not walk properly. even more so you could night ride at all.
