Outstanding quality and construction collar insignia set for an NCO of the SS Regiment Deutschland, who in the earlier years of the SS-VT, wore a "1" on their SS insignia side.  In later years, this "1" was done away with, as the SS-VT were incorporated into the Waffen SS.  Many tabs imply had the "1" removed (picked out by hand) and then they simply began manufacturing tabs like this without numbers whatsoever.  This set is not upgradable.
