There is a German helmet that I made on http://www.buckrogers.demon.co.uk/3d/gh.zip . It has a texture map, so you can put your own color patterns and logos on it. It is a Poser model (not a prop). It has an (anachronistic) posable riotsquad visor, but you can delete or hide this if you don't want it. See http://www.buckrogers.demon.co.uk/3d/spmanfl6.jpg for 2 men wearing it.
