They could still be 4 or 5 though, rather than 6.

Wikipedia claims that they were done by riveting lots of small metal plates together.

At that point, the helmet-makers started adding paper-and-wood ornaments () on top of them.
That shouldn't matter though, because samurai in Dominions need a boost, and having to pay for a tower shield (3 res) without getting the benefit doesn't help.
