Another of the "when was the Swastika added" pieces.... DSB Gau I Ostpreussen. I've seen them with a variety of different style Swastikas in the centre of the S, or treble clef, & also without a Swastika.... Marked on the pin plate to Carl Poellath, Schrobenhausen. Quite large badges around an inch & a half. There is some damage to the Swastika on this one, possibly an attempt to de-nazify it?
