I recently recieved an 1914 iron cross 1st Class: When I first got it, it seemed pretty normal; magnetic core, silver edges and back, marked "KO" etc. However, when I looked closer, it seemed slightly odd; the back pin had been replaced (as denoted by the tarnish around the hinge), and the frame didn't quite fit the magnetic core. At first I thought this was fairly common, since I had seen similiar things around the forum, and I presumed it was simply an early imperfect iron cross which had had some adjustments (i.e. the back pin). However the next thing really stumped me; the medal's documentation. Having been awarded around 1920, I assumed it was simply a delayed processing award that had only recently been awarded. However when I looked at the award certificate, it seemed a little strange. First of all, the stamp on the paper is different from other similiar documentation for iron crosses from that period. Secondly, the wording denoting who the award is from is crossed out, and the initals of the man who awarded it have been changed. Any ideas? Could this award be one which was unofficial, as denoted by the "adjustments" to the certificate?
