Erkennungsmarke 1./Pi.Ers.Btl.9

Nice original Erkennungsmarke or ID disc marked 1./Pi.Ers.Btl.9 indicating 1. Kompanie Pionier Ersatz Battalion 9 which fell under the 159 Reserve Division which was stationed on the Atlantikwal and suffered heavy casualties as it withdrew when the allies landed in southern France. The tag comes with its typical cord albeit shortened. A nice piece with possibility for further research.
