I have many many more slings, belts, holsters, military WWII, WWI, Vietnam war, etc listed. Here is a unmarked WWI or WWII era leather rifle sling. There is wear and tear, but the leather is strong and still soft. I think this is for the M1 Garand or Springfield rifle.
IF THIS IS NOT CORRECT, PLEASE LET ME KNOW. I'M NOT TRYING TO SCREW ANYONE. I'M JUST CALLING THESE AS I SEE THEM.I'M NOT A RIFLE SLING EXPERT. Please see pics for more details. I HAVE NO CONTROL OVER IT.
