A Waffen-SS Rottenführer’s Rank Chevron

The insignia is constructed of two diamond-patterned silvery/aluminum chevrons; they are a different style- the outer chevron appears to be machine-stitched while the inner chevron appears to have been added at a later date by hand (due to career progression); both chevrons are attached to the black wool backer via white threading; measuring 68 mm x 78 mm; uniform removed; very fine condition.
