I have the same case.

I was told that these modified 50 BMG cases were made in Germany

AAA Ammunition of Omaha Nebraska, USA. That .50 BMG caliber headstamp is commonly available commercially in new primed brass for shooters and reloaders of the caliber. AAA necks and sizes that case for .460 Steyr applications.
