RARE Army/Waffen-SS Belgian collaboration 'Wallonie' volunteer sleeve shield

One of the rarest volunteer shields to encounter, worn by first the Army (Heer) volunteers of Wallonia and later by the Waffen-SS Sturmbrigade Wallonien. The sleeve is a light worn, uniform removed example, made by the Bevo-Wuppertal company, picturing a flat-woven Belgian flag with the letters WALLONIE above.
