Der Stahlhelm, Bund der Frontsoldaten - World War I Frontline Veterans' Association
A fine enamel badge issued in 1925. The enamel is nice, without any visible damage.

"Ges.Gesch" = Gesetzlich Gesützt, i.e. protected by law marking.
On the back is the membership number 1361 and the date of entry 1925.09.07
