Thank you, Dave, for that information!
It also appears that the Pack Christmas daggers, all already had a steel based scabbard. This way they avoided what is seen in the picture: the earliest Eickhorn scabbards being made out of a copper alloy, easily got banged up.
So it could be, that the Pack daggers were a second order made by the SA, after the problems they experienced with the Eickhorn daggers...
Best regards,
