As the title asks, i'm trying to figure out how and when certain types of armour were utilised in the 100 years war around/ after the time of joan of arc

my purpose is to compare t a recent anime series known as maria the virgin witch, a series about a witch attempting to quell and prevent battles between england and france. the series has very well drawn designs of weapons and armour. iof the 15th century however my question is whether the designs of armour, such as the use of sallet+ vbevor, armets, some varients of gothic plate etc. were used in that period of time after the death of joan of arc since the protagonist mentions her death

https://www.youtube.com/watch?v=mukG1RA74jQ and here shopwing a battle, it doesnt say the name or anything., or where however one french minor character mentions that the french are pushing towards calais in a meeting with the witch prior to the battle in the video

my suspicion peronally is that, like skallagrim says there is a very good level of attention to detail for historical arms and armour.. however i fear that what is being shown is a little too late for the hundred years war and would look more suitable if the series was set in the war of the roses

note maria, and all the other witches and succibui etc are completely innacurate in their look or clothing, the creators have gone full anime grade costume design for that, its the normal french and english peoples that are rendered accurately

The source he shows for jack chains is Memling's St. Ursula shrine, which dates to c. 1489, Joan was martyred (or executed) in 1431. Early sallets and armets appear by the time of Joan's death, but aren't really as popular as great bascinets and kettle helms for the late 100 Years War.

Really bizarre show. The attention to historical detail completely stupefied me, considering it's an anime about witches and succubi. The fact that the realism is juxtaposed with outlandish fantasy elements creates a jarring effect, but I have to say I'm a huge fan just because the creators obviously put the research time in. For anyone interested I watched it here: https://www.youtube.com/watch?v=ZVcTzyO3U70&list=PLwazKLaN7rLicoapnHpu-ZQHCD9ipe3cY

The Hundred Years War is generally considered to have lasted until 1453, and it seems like the show is set in the last decade or so of the conflict. I might be wrong since I've only watched two episodes, but if that's the case, then the armets are correct. Nicolle argues for the armet as early as 1425, but even if you don't subscribe to that theory armets were certainly in use by the 1440s. Here's one at the Met.

The sallet/bevor combo is correct as well. It was used since 1430. Check this old thread for more info and sources: http://www.myArmoury.com/talk/viewtopic.php?t=5998

Calais and its surroundings was a hotbed of military activity throughout the Hundred Years' War, so it really doesn't help in establishing the time period. And "in retreat" might be something of an understatement when it comes to the English position in the last decade or so -- as a matter of fact, the last major battle at Castillon was fought by an English army that invaded to retake Gascony, which had been lost to the French (along with everything else on the mainland apart from Calais) several years before.
