Pioneer Signals Specialist Sleeve Patch

Pioneer Signals Specialist Sleeve Patch - Black Embroidery on Wool
An authentic, unissued German army signal operator's proficiency arm patch (Tätigkeitsabzeichen für Nachrichtenpersonal). This outstanding variation is constructed on a dark green badge-cloth wool base, featuring a tightly machine-embroidered lightning bolt (Blitz) in deep black thread. The black embroidery denotes a radio operator or signals specialist assigned directly to a Pioniere (Combat Engineers / Pioneer) unit, identifying the soldier's specific communication role within his branch formation.
The reverse of the patch shows the textbook factory assembly, featuring a secondary layer of raw white stabilizing material and a black perimeter thread track to secure the embroidery onto the wool base. The patch is in immaculate, mint condition with crisp edges, no fading, and zero moth damage. Sourced directly from the recently discovered German tailor's archive (Schneider-Bestand).
