Beautiful rifle. I was excited to see that WR offers a traditional hook sling in leather. Most of my rifles were made for them and I own only one, and that is too short and too narrow for many of the rifles, given it was made for my smaller 360EX Watson.

Not cheap but hooks alone go for $100 or more US$ on EBay, with no sling.
