Just for shits and giggles, I just ordered a 15 from the shop today. BCP grind (top edge sharpened), N/S squared single hilt, N/S butt cap, stag w/finger grips, and all black spacers. It'll be a beauty too . . . Five years from now. Argh!

Whoa. Twenty questions here. OK, let's see. If you don't like brass, nickel-silver is your only other option. But it's significantly more expensive.
Your knife is NOT a CDT. For most purposes, it doesn't make a whole lot of difference whether it is or isn't, but the "stock" 15s have a wider tang, which some would argue makes it more sturdy.
Stainless versus carbon steel. Well. We could go on all night about that. We average 13% humidity here, so rust is not an issue. In that case, yes, the 01 steel is better. If you're in a place where rust IS a factor, I'd look pretty hard at stainless. (Little-known factoid: It's forged 440B, which doesn't suck.)
And no, your photo looks nothing like the knife I ordered.
Bruce, the word I hear from the shop is that they are, indeed, using 440B "for most knives" now, as it can be forged and the 440c apparently cannot. I'm no expert on these things, but presumably the folks at RMK are.
Sounds like you made a nice choice with your knife.
