The last one for now, here are some badges for the Leistungsvergleich [Proficiency Competition] held by the DRK-Landesverband Baden-Württemberg [DRK State Association Baden-Wurttemberg] in 1974, 1976 and 1980.
I don't know how long these have been issued, but I have seen them for various years from the 1960s to the 1980s as well as badges for an "EH-Wettbewerb" [First Aid Contest] that are identical except for the inscription.
The badges are of nice, heavy quality (which is why I tend to believe that they were presented to successful participants rather than being mere day badges) and bear the maker's mark for Alois Rettenmaier of Schwäbisch Gmünd:
