So the pointy helm is what is called a Bascinet. They come in a bunch of different variations. The one i have is referred to as a Wenzel Bascinet due to its depiction in the 15th century Wenzel Bible.
I did not make them unfortunately, but I did paint and weather them. The bascinet was completely unwearable and inhisthoric. I had to do a lot of work to it to make it wearable. If you check my comment history, you can pribably find the wall of text in which I describe everything I had to do lol.
Also, the helm with the flat top, typically referred to as a Crusader Helm, is a "Great Helm" I wear that one for my crusader armor which is a very anachronistic 12th/13th century setup.
