German WWI Iron Cross 1st Class, KO Mfg.

Original era manufacture. Magnetic center EK1 with a german silver frame and backing. Most of the original finish remains on the core with a silver patina to the frame. KO mfg. mark on the reverse on the lower arm of the cross. At some point, the original owner removed the original pin and had this very nice horizontal pin installed by a jeweller. I really like these personalized crosses, almost kept this one.
