I understand that this type of armour was quite common in Europe during the first half of the 14th Century. You can see examples of this in some grave effigies from the period.
I've done some leather work in the past, so I thought that this is something I could definitely do, but it has taken quite a while. In total there are 56 rivets that all need to be cut to size and peened over. I'm quite pleased with them, but wish that I'd had some veg tan leather to use. Hopefully they'll look a bit better with some wear.
