I still think I would leave the original subject rifle as it is, but for the sake of discussion, here is an old rifle with tacks and rawhide:

I know, I know... It's a Model 1866 Springfield (an "unmentionable"), but we're just looking at the tacks and rawhide. This rifle is evidently missing a barrel band, and its native owner secured the barrel with the rawhide wrap. Here is a detailed look at how the hide was stitched on with sinew:

The tacks through the hide were likely not necessary to secure it, but the owner probably liked the way they looked.
Thank you for the tip! That is actually a pretty decent price for that amount of good quality rawhide, and I found they give a choice of two thicknesses.
Best regards,
