Is this an authentic Erkennungsmarken ? This is my first and I understand these are easily faked. I have tried to research the disc and my best guess is that it is the Armee-Nachrichten-Regiment 558 (Army Signals (message) Regiment 558). The disc comes from the Kurland pocket area.
Any assistance or information about the disc and the regiment will be greatly appreciated. Also, are World War I discs routinely faked?
Thanks again!
