as you can see here, the 'mohawk' is even less big than it was on the reference!
gladiator helmets all had limited field of view. they are designed like this. This one is particularly limiting, but yet it's a real model. it's an Hoplomachus helmet
of course it's not all solid. it's only a sheet of metal that has been given some form..
I made a big search for references, and I have many many... (and I'm sill reading on gladiators, and looking for pictures).
