You can get:
++ 2 styles of chin strap (one side looks hand made even!),
++ An ill fitting Kurassier spike (Replica???)
++ A civil shell with an interesting hanger on the inside of the neck guard...
++ and... not having a Hessen helmet of my own I don't know about the plate, but would suspect it's a fake (?).
Quite the deal! You certainly know how to pick out the premium deals on ebay!
