Bo, I'm not quite sure, but I think, hard gun cases were not common in Germany.
More in use were gun sleeves and the so called "Schinkenkoffer" or "leg of mouton" from hard leather, also for take down guns. This one on E-Gn is typically:

Schinkenkoffer E-Gun

or this one, two parts:

Schinkenkoffer two parts

This one of softer but thick leather is my own:

Soft take down slip

The hard gun case is more british, I think, but perhaps I'm wrong.

Cheers,
Wolfgang
