This is a N.S. Frontkämpferbund (Stahlhelm) Urkunde über die Verleihung des Diensteintrittsabzeichens des N.S.F.B.S.
It is a little wrinkled.
This particular citation was only in use for a short time around 1934. The image of the particular N.S.F.B.S in the left upper top shows this as well. This badge and the here offered citation were only in use in the last year of the existence of the Stahlhelmbund/N.S.F.B.S.
Very rare to find and much rarer then any of the previous Stanhelmbund Diensteintrittsabzeichen citations.
