The gun is made in Bohemia and has Austrian proof marks which would make me guess that it was made before 1919. Someone adept with Austrian proofs could tell. But the barrels are German and were proofed in Germany. Somebody tell me how that works. A Wanderpreis is a traveling trophy or award that the winner doesn't get to keep. Hard to believe with a gun, though. If you ever see an Austrian gun marked "Jen Pro Broky," it means the same as "Nicht fuer Kugel" or "shot only" in Czech. Donauwoerth is a fur piece from Kriegern but then the gun is a wandering prize.
