Great example of an early Iron Cross 1st Class (EK1) produced by the firm (Klein & Quenzer, Idar Oberstein.) Made of a three piece construction with magnetic iron core. The reverse hardware pin is not maker marked, though this is defiantly a K&Q made piece. Great condition with no damage or repairs and a nice uncleansed layer of patina. A great piece that will display nicely in your Iron Cross collection.
