Curious about this mark

[Gary C.]

Just cleaning up some things given to me by a long ago neighbor and was wondering what this mark might indicate.
Thanks in advance

It looks like it was re-steeled with a file at some point, but I'm not sure what the Iron Cross stamp is for. Maybe it was supposed to indicate it was made in Germany?
