I didn't know early American guns could be ordered with slings. Good to know, thanks. I just got a Lefever H straight grip 16 I'm setting up as a chukar gun. It is a lower grade gun, so maybe attaching swivels wouldn't be such a bad idea. I do have a sxs barrel swivel in great shape that I could use. Drilling and tapping the rib makes me nervous though. I'm primarily a chukar hunter, and slings on long 5-10 mile hikes in rough country are almost a must.
