That would be in reference to R.L. Wilson, I think. His ethics aside, he put together some very interesting books. I've found a few historical errors in the texts of a couple of them, but the photographic work was uniformly outstanding. I always wondered how in the dickens he got access to all of those guns and artifacts.
Speaking of artifacts, here are a couple more old guns with tacks. I'm pretty sure this one is a Leman "Indian Rifle," although the curator just called it a "percussion plains rifle":

That rawhide on the wrist looks like a thong wrapped around and around, but if you enlarge the photo, you can see it's a solid piece, evidently stitched on the bottom side, with the stripes painted on.
This old Northwest gun has a very understated tack pattern, at least on the side that's visible. Just a few tacks outlining the butt, and a few on the forearm:

We note the actual buttplate is missing. Most museum curators will tell you the buttplate was removed "to make a scraper." Indians evidently used a lot of scrapers...
Both of these guns were previously in Frederic Remington's collection. I think I recognize the rifle in Remington's image of "The Old Trapper":

...and this might be the Northwest gun in his picture of "Gingras, the Trapper":

Both of the firearms are in the collection of the Buffalo Bill Center of the West. Here are links:

If you go to the link and click the double arrow above and to the right of the photo of the gun, it will bring up a larger image with additional navigation keys to enlarge it even more. You can really see the details that way. Maybe it's because I'm red/green and blue/green color blind, but clear black and white images bring out more fine detail than I can ever get from a color picture.
Best regards,
