Nice 1st Class Iron Cross by 26. This indicates the maker B.H. Mayer. Does show a healthy patina from age and wear. I think it looks great as is but certainly could be cleaned up by someone who prefers. I like crosses in this condition that show the halo on the outer edge of the core along the silver beading. I don't believe this can be reproduced and is something I always like to see. Cross gently convex in shape. Nice, honest example.
