Rare variant (possibly field-made) zinc id tag (erkennungsmarke) of the 4./E.L.A.H., which means the 4./SS-Infanterie-Ersatz-Bataillon "Leibstandarte Adolf Hitler" in Berlin-Lichterfelde.
This was the training and replacement battalion of the LAH, and the 4th company was a heavy machine gun company. We have not encountered such variants before (usually "SS-Verfügungstruppe" is stamped on the backside), but we believe it to be a rare original tag.
It was supposedly found in Russia, but the precise location is not known. For that reason, no exact spot was marked.
