That's a real beauty!!!! Such beautiful bone on a scout knife.
I can't put my finger on the reference right now, so somebody help me out if you have one. But if I remember correctly, the master cutler for Remington came from Sheffield, England, and likely brought the pattern with him to Remington from Europe, along with a number of other patterns. Inspiration for the pattern probably came from old hoof pick knives and/or maybe old Victorinox designs. At least that my story, and I'm sticking to it.
I don't think there's any official name for the pattern. I just call it a "gentleman's scout" because that's how I see the pattern. It has all the earmarks of a traditional scout, but is executed in a more refined way with additional complications. It's a really, really hard pattern to manufacture traditionally, but is absolutely glorious when done properly.
