Hi Spacey,,it is standard,, as that little grip loop was used for vertical carry,, for parades or hiking etc. Most SA men chose to take off the little grip loop and wear the dagger on a 45 degree slant as you see in pictures when standing guard or at party functions. Having a 2 pc hanger as you have is a nice find,,,,finding a dagger with a 3pc hanger is a little rarer. It was up to the owner and depending upon his service function location,,that decided what use and how much his dagger would swing around ( due to his movements).
Your dagger looks to be an early dagger with a late scabbard. The grip is beautiful and the hanger is in great condition. Very nice Spacey!!,,, who is the maker..just curious. Regards Larry
