Any more luck with the back info? MSSTE translates to a Norwegian word though. Also all of the Griffins I find face to the left (their right our left) Not the way yours is on the medal. There also appears to be a blue product on the medal, perhaps some type of enamel that has worn off. Blue, or AZURE is very popular on Norwegian and French medals. Still digging!!
Also sorry in advance I do not want to seem like a jerk but the design is called a Maltese Cross. Of course Iron Cross has too many German (WWI and WWII) links to it. Again not pompus just factual. To help us define the item.
