Here's a link to an EM m43 black panzer cap http://www.lostbattalions.com/german...MM43PzHat.html the officers cap is the same but with silver pipeing around the edge of the top sometimes around the edge of the fold down flap as well.
and here's a DAK(Africa Corps) cap http://www.lostbattalions.com/german...isorEMCap.html
