I see some of the "rare" type no.1's selling for more dollars than one would think. Not completely sure that the internet sales actually went thru or not, really none of my business, always all kinds of sales you know.
I bet that 257 R dolled up to a "S" version was kinda neat from a cosmetics point of view. However still is a 400-425 dollar doner plus say 65 for the rib, 15 for the sight, 35 for the front ramp, 20 in front sight etc, and perhaps 18 for the barrel band. Hard to believe a 100 bucks to blue the works. Still a ways short of a k buck. I do my own work, so the effort to assemble is free really, and somewhat glad of that. Probably would have been enhanced to some with a new barrel, but some of the new oem barrels would suffice in some circles.
Been thru the long waits and big $ on some gunsmiths on oddities I wanted, so just learned to do it myself. Hopefully the guy that bought the made up 1S did not get too giddy with his buy, but been there and done that when I was much younger. Been in those circles of getting convenced to buy high and sell low back to the same guys, just moved on to more basic things...plus never sell what you buy in No.1's.
One of the nice things about the no.1, any action can become what you want it to more easily than some action types. I think that is what appeals to a lot of folks that appreciate them for what they are, a nice looking shooting gun.
