This helmet is one I no longer own, a visored bascinet made back in the early days of when I took part 15th Century medieval re-enactment.
These photos were taken in June 1987
This helmet was excellent to fight in, providing good protection and freedom of head movement, some of that down to the fact it was not a accurate reproduction.
the quality and historical accuracy of this helmet would not get past most re-inactment groups standards today.
