I am sure taht someone out there will correct me if I am wrong, but the one without swords is for the youth group (NSUF Nasjoanl Samling Ungdoms Fylking) and the one with swords is for the little girls (Smahird) and male youths (Unghird).
I have shoulder patches for these groups as well.
The last one is for the Unghirdmarine, or sea youths (I guess we would call them Sea Scouts today).
