WH (Heer) FLAK Artillery EM's Shoulder-Strap

Wehrmacht (Heer) 'M40' type EM's shoulder-strap (Schulterklappe) having the red coloured silk-type piping as intended for an 'Soldat der Artillerie', in this case a member within a 'Heeres FLAK' unit. The shoulder strap is complete with its original slip-on (Überschübe) indicating a member within the 'Heeres-Flakartillerie-Abteilung 274'. The strap is executed in fieldgrey wool and comes on its functional tongue, the straps is measuring approximately 12 cms in length. The shoulder strap unfortunately shows heavy moth-damage, see photos. Still an extremely rare original shoulder strap which is hardly ever offered for sale and would be a great addition to any insignia collection!
