Some parts are authentic, some are not. We'd need more pictures to be certain, but this is what I see:

Blade: Probably bad. The trademark is too far off the crossguard and does not look correct.

Grip: Not Eickhorn early production.

Guards: Not Eickhorn early production. Maybe later EP&S

Tang nut: Probably fake, Maybe early EP&S

Scabbard: Real, but a Later RZM scabbard reworked with an unlikely 'motorcycle' finish

Hanger: Fake. Maybe clip anf buckle are real ?

Don't buy this ... or get a refund
