David, there are dozens of plane makers capable of building better planes than a Norris. Either by hand or with the aid of CNC. The value of a Norris lies in its name. Ditto an instrument played by any famous musician. It's value lies in being owned and/or played by a famous name.

I get what you're saying, but you asked whether the instruments had value. One of the vintage guitars that clapton has that's original would still be several hundred thousand dollars.
You also asked are they any better than other guitars....yes, they are. It's a bad comparison with this norris.
This is a collector/antique thing and not a matter of competence in use. And in this case, the tool was impractical from the start - that was the nature of my original question. The fact that it was impractical for planes instead of making the tool less valuable (which is the case for uncommon guitar goods that were expensive and not good from the start), it makes a tool more valuable. There are other parallels to this, like rare farm equipment - the odd factor makes the equipment valuable, and there is a market - retired farmers who have had the luck of amassing a huge farm and then selling the land - that drive the prices to stratospheric levels.
I could build a plane that would match the norris, but it would be impractical. I could build a functional plane that would match any ever made, even by holtey sans adjuster (no interest) and make it as flat as a starrett could show, and then add some hand biases that may not be in some of the more common boutique makers.....but I wouldn't necessarily have the patience or desire to really make every part of the plane photo perfect in surface finish in and out. That's a pain and that's the difference between sauer, holtey or norris (again, sans adjuster - karl is bonkers about trying to get a poorly designed adjuster made perfectly to cover some of the issues with them).
None of the boutique makers' planes are technically better than a norris with a ward iron, though. The norris may have moved a little over time, but that's minor with steel dovetailed planes and is something even I could correct without resorting to machine tools.
This is a similar notion to japanese chisels or japanese razors - there was no real market for aesthetically ideal chisels 60 years ago. The improvement in kiyotada's chisel aesthetics and all of the $600 per chisel makes that are around now are due to marketing to people from the US and western europe. This is the parallel with holtey's planes - the improvements would be not functional to even an intermediate woodworker. As far as the japanese chisel comparison goes, I have a new late kiyotada chisel. It is an excellent chisel. I have learned to heat treat that type of steel in the open atmosphere better than commercial schedule results, and the older chisels that I fish off of japan's ebay are in the same class as the prettiest of tools now.
This focus on aesthetics is a matter of selling to amateur markets by enterprising individuals, whether they're the seller or the maker.
