Here is something a bit unusual.  A shoulderboard for a Schaftsfuhrer, but instead of the usual red piping indicative of a typical 1938 Allgemeine, this is edged with silver piping.  This is tentatively identififed as H.J. Freiwillege Feuerwehr (fire brigade). 
 
The owner had bee promoted to a Schaftsfuhrer as there are two holes down the centre line where a single pip was mounted.
