he best thing, of course, would be to refer you to photos of actual helms from the archaeological record or from contemporary illustrations. However, access to these on the net is somewhat difficult to getKiev helm the Wenceslaus helm on Halvgrim's site at
http://web.missouri.edu/~rls555/RUSH/helms.htm but this is the only one on that site that fits with what we think of as "Norman" helmets. The Bayeux Tapestry as at
http://www.hastings1066.com/bayhi4c.shtml shows many of them, but in too little detail to be of much value. There are in fact many helms of this type in the archaeological record if you know where to look, unfortunately a litle hard to access.
Much as I hate to say so, probably the most easily accessed pictures of actual helmets are in the Opsrey book "Saxon, Viking and Norman" - just be sure to look only at primary source pictures and not to take any notice of their reconstructions, which are often suspect.
