NSDAP badge with marking M1/78 - Paulmann & Crone, Lüdenscheid

NSDAP badge with marking M1/78 - Paulmann & Crone, Lüdenscheid. A transitional type issued about 1935 as it has an additional marking of GES. GESCH.  Excellent condition. The manufacturer is considered to be neither the most common nor the rarest one. But the badge is interesting itself because it's a rare type of the transitional badge.
