I got these as a set a couple years ago. They've both been repaired and had parts replaced. The shell is unit marked 1.K.2.42. The cockades look to be repros. The chinstrap looks original but the catch is missing and they are held together by an unattached pin. The liner is likely a replacement. The fasteners for the spike are completely wrong. The wappen may be original but I'm far from an expert. I'm curious as to what folks think about that. The nuts are definitely wrong, they don't even match each other.
