I found these stripes a few months ago whilst out detecting. The area (2km SW of Hiddesen near Detmold) seems to have been used as a british training area for a time post-war (loads of .303 and 7.62 blank plus UK type trenches). The material is aluminium with brass attachment prongs. Has anyone come across this type of rank badge before? I'm assuming that they are from the 50s or 60s - possibly RP?
