Oswald rifle sling

I am interested in making a reproduction of the USAF M13 shoulder holster strap that LHO made into a sling for his Carcano. If someone has one, I would be interested in getting measurements and even pictures if you can swing that. I saw here someone had made one and was selling it with a Carcano 91/38, but it wasn't a very good copy. I think I can do a better job with some accurate info. Thanks.
