I believe this to be for one of the Polish WZ or Mauser model rifles from WWII or just prior. Buckle is steel, which seems consistent with Polish. Steel button is present and in good condition. Leather has the fish scale/crosshatched pattern similar to what’s seen on German slings. It’s in solid condition and suitable for careful use. Sling is 57 long and an inch wide.
