Hey Patrick,
This one has been there for a while.
IMO, it's about $300-$500 overboard and the Uberzug + chinstrap + liner look too freil or dry for me to even think about it, not to mention that front visor's broken trim and the Prussian cockade which looks too minty compared to the rest of the helmet, to say the least.
Apart from that, the rest seems OK but someone needs to validate the markings.
