Sling Use -- Whelen Rifle Sling

[Hawkeye6]

OK. I'm not sure where to post this, but here goes. I have a question about rigging a Whelen Rifle Sling. I bought it from Hunter, but there were no instructions on how to set it up.

It is sort of like a standard leather military style sling. I think the USA calls that the M-1907 sling. And I know how to set-up and use that. This is an offshoot (pardon the pun) of that sling developed by Townsend Whelen. Instead of using two straps, and two frogs (or claws) it is just one long strap and one frog. Supposed to be simpler to use, etc.

I think I have it set up right, but if anyone has some ideas or references, I'd certainly appreciate the help.
