This is a scarce and highly deirable pair of collar tabs. Saar and Prag were the two motor formations that were allowed to have the full name of their location on their collar tabs. This pair is from Motorsturm 14 of Motorstandarte Saar. The rank is Sturmfuhrer which is the lowest officer rank on the NSKK scale. I believe this particular unit with others were combined to form the motorized group Westmark. Such NSKK units were basically training grounds in which the panzer and motorized formations of the military drew their personnel as well as other tasks. This pair has matching buckram backings and are in great condition with well sunk in devices. Comes from an advanced collection and scarce enough I could find no other examples available for sale.
