Pretty simple - can't be original, since the person who engraved it couldn't speak German. It would read "Meine Ehre heißt Treue" and not "Meine Ehre heisst Treue". The "ß" is a German letter and replacing it with double S is incorrect. If presented to a high rank person with engravings at this class one can assume they would be able to not make typos...
Only Stug would post something like that up lol!
Would go perfectly with this one.
Two beautiful parade weapons. Just not sure for what kind of parade. Gay pride?
