Hello,
Great badge! In over 40 years of collecting HJ Württemberg I have never been able to acquire this one.
The badge most likely (sehr wahrscheinlich) comes from a HJ leader camp. Around 100 HJ sub-leaders from Unterbann VII/121 (Ludwigsburg) met in mid-August 1933 in the Glemstal near Schwieberdingen. The camp leader was Sub-Ban leader Bühler.
