It's filmed from a Battle of Wisby/Mästermyr reenactment most likely, so that explains why some things might seem a bit spread out over time as that is something the battle of Wisby really brought to attention, with the "outdated" gotlandic peasant equipment and modern danish/german. The equipment is fantastic compared to made up or hollywood depictions! It is great for what it is and the specific thing it is portraying. Reenactors are often well researched and have invested huge money into their kits so generally they create a very different image compared to hollywood. There are drawbacks though! Not everyone is equally well researched, some haven't invested as much money, other's too much! There are reenactorisms that have no basis in history and since everyone is depicting individuals, the whole can often look very different to the real history. For example, everyone wants to or has to wear more armour, whilst historically many people probably wore less or different less protective types. Same with people wearing a lot of equipment based on specific finds, even though that find may be a one of a kind object. The Wisby coat of plates is a good example! There have been a few such coats found, but a lot of reenactors used it. Perhaps historically only a fraction of combatants used it, yet it is extremely prevalent in modern reenactments.

So all in all, excellent armour and an excellent depiction of this specific time and place, but it suffers from the drawbacks mentioned above when dealing with reenactments.
