Iron cross 1st class by Klein & Quenzer, Idar/Oberstein. Three part construction with magnetic, iron core. Maker marked on the pin with the PK code of K&Q "65". Excellent condition with a fully black core and a frame with only light patina with the polished parts still shining through. No repairs, no damage. The cross comes in a black K&Q maker marked EK1 box with EK1 silhouette on the domed lid, very unusual case!!! The case remains in very good condition. 

Very nice, fully matching set in excellent condition!
