I HAVE VARIOUS DATES AND I WILL CHECK IF I CAN FIND THE DATE YOU NEED TO MATCH YOUR RIFLE. I CANNOT GUARANTEE THAT I WILL HAVE IT JUST SEND ME A MESSAGE PRIOR TO BUY IT AND I WILL CHECK FOR YOU. FOR EXAMPLE I HAVE SLINGS DATED FROM 1932 TILL1962. THEY ARE ORIGINAL SWISS ARMY SCHMIDT RUBIN K31 LEATHER SLING WITH BUCKLE IN USED GOOD CONDITION. THOSE SLINGS ARE THE SAME FOR THE SWISS RIFLE MOD. 1896/11 RIFLE AND I HAVE SOME SLINGS WITH EARLY DATES FROM 1914 TILL 1930.
