Could someone tell me where I can find an old, medieval helmet for a poser figure? Any would do, but one of the ones that are kind of pointy on top and have the thing sticking down to protect your nose would be preferred

There is a Greek helmet very nice at Greylight Follow this link: http://www.greylight.com/poserheadgear.html

Thanks, that's really helpful. I'm still interested in some more though, because that one may look a little TOO greek (although I'll still probably use it). The crown on the page was also helpful

I think you're looking for a norman conical helm (bullet-shaped with a nose guard) or maybe a spangelhelm (bullet shaped, nose guard plus cheek guards). Used one on my Norman Knight model (the pic's in my gallery if you'd like to check it out). I could send you a dxf file if you're interested. Also saw another model at fairywoods, on another norman knight.
