This GEM condition 2nd Model Luftwaffe dagger is in almost perfect condition - no single flaw to point out, just ultra-minor signs of wear.  I'd rate this piece in the easy 97% or better category.  Reverse cross guard has the initials E.O. v. Sch ... possibly researchable, given the family crest that is expertly inset in the center ... a small silver oval featuring 3 Oakleaves growing on what looks like a planet.  Great research project!  This dagger comes with a very high-quality deluxe set of hangers.
