New Swadian helmet model ?

[Pikeman]

As devs use to say: find an OSP texture for it, and they'll look at it.

I have no idea how to find that or in general what that is, but i saw the helmet from the picture i posted above in countless of other warband mods, so i guess it won't be so hard to find it ( i might be wrong ) . But any helmet except the one we already have (example : open trooper) will probably do.
