In this forum there is a list of Tiger deliveries:
Tiger im Focus » Fakten » Zahlen und Daten » Zuweisungsliste Tiger I und II
There were a few delivered to SS-Ersatzheer. Maybe to the SS-Pz.Ers.Abt? If so, some of then fought around Paderborn, and maybe joined the SS Pz Brigade Westfalen. Is this history written already?
