WW1 Iron Cross & Honour Cross Pair with Buttonhole Bar.

A wonderful court mounted pair comprising of the Iron cross 2nd class (EKII) of typical WW1 type suspender ring maker with KO for Königliche Muenzamt & Abteilung Orden of Berlin. The Honour cross or Hindenburg cross marked on the back 'DRZHEIM'. I must have handled may hundreds of these crosses and I have never seen this mark before. It must be a scarce issue. If you know who this maker is, please let me know. Also, with this pair came a buttonhole badge with ribbons for both medals and crossed swords device.All in very good condition, the Iron cross being a superb example.
