Extremely nice Iron Cross First Class. Pin is hallmarked 18 for the firm Karl Wurster KC, Markneukirchen. Great overall look with just the gentlest of oxidation along the beaded edge and in the corners right where you expect to see it. This is very light and, if anything, I would say adds to the overall appeal. If the back has ever been cleaned it was a very long time ago. I can find nothing negative to say on this fine looking EK1.
