There was a time when US brands like Stetson or Resistol licensed Wegener to produce hats for the German(European) market.
This one here is a 1960's Resistol that was made by Wegener. The color in the photos is not really acurate, as there is a slight green touch to the brown, which was not captured by the camera.
There were some serious moth nibbles on the brim, so I added the black lining to cover the disaster area.
