Very nice half zinc Erkennungsmarke from a member of SS-Grenadier-Ausbildungs-und-Ersatz-Abteilung 15, the training unit for the 15. Waffen-Grenadier-Division der SS (lett. Nr. 1). The unit was raised in November 1943, when the 15th Latvian Division was formed and was stationed in Jelgava in Latvia.
It is curious that it was called an Abteilung, and not Bataillon, but it existed as such. The tag was found near Staraya Russa, where the 15th Latvian Division was fighting at the beginning of 1944.
The tag is in good condition.
