NSDAP membership badge, button hole type

Original WWII German NSDAP membership badge, button hole type. Nice enamelled example with red outer border and white centre, featuring a black swastika and “National-Sozialistische-D.A.P.” lettering. The reverse retains its original attachment and shows a maker’s mark at the bottom. Shows some honest age and wear, with some enamel loss to the front, but remains a nice original example in good condition.
