Outside image hosting isn’t allowed because when the link expires, the photos are lost and the thread becomes useless for future reference.

I can’t help with authenticity, but the abbreviation stands for - SS Grenadier Ausbildungs und Ersatz Abteilung 15

There is some information (in Polish) here -
