German18.SS-Freiwilligen-Panzer-Division (SS-Volunteer Panzer Division)-“Horst Wessel” Collar Tab A seldom encountered tab, with a black wool/felt backing, and the runic-looking “SA” insignia machine embroidered in silvery-grey thread directly onto the wool surface. There is some light soiling to the wool surface. The reverse has a buckram-like stiffener, but it is quite thin and no longer very stiff. The white stitching that indicates the tab was probably made at Dachau. A sharp-looking, rarely encountered collar tab!
