Thanks to Jim W and Frogprince for this information. I think that your both right. I got this dagger from a collection of a deceased WW2 Vet. Along with this dagger I got a 2nd model Eickhorn Luft with hanger and portepee,a Eickhorn army with hanger and portepee and a Curt Hoppe SA dagger with leather hanger. The German daggers are in super condition and authentic. The cousin of the Vet didnt know what it was or were his cousin got it. I pretty much got this dagger as a freebee. Thank you
