Very interesting photo and dagger. It does seem to be the RLB EM scabbard here but it could also be the Postschutz scabbard without the center fitting. At any rate a Postschutz blade is a lot longer and quite a bit wider at the crossguard then an RLB EM and I don't think it would go in the scabbard. It could be an RLB type EM blade though. Also interesting about the rank-someone should be able to tell for sure from the collar tabs.
