Interesting Ausweis issued in 1941 to a Dutch worker of the Sudetenländischer Treibstoff-Werke AG / Hydrierwerk Brüx. Both companies were German companies under Nazi rule that manufactured goods from oil such as gasoline, synthetic materials, fuel, etc. Ausweis is in awesome condition, laminated and with photo of the owner, who was a worker but we don't think he was a slave laborer.
