Was today metaldetecting with my friend. He found a muffy iron plate about 2cm x 4cm size. He went back home and washed it. This cropped image is the part of that pressplate where there were still letters seen. I flipped the image so this is the mirror image where you can read the text you can press with it. I figured out what is the text in full. Press the image and open in new window to see it better.
