Stunning build. Agree with the 'arts & crafts' sentiment, respect for dealing with it!
You probably know this already, but your Chris King has a 'GripNut' bearing cover which works differently to a normal two-nut headset and won't work properly with spacers.
You'll have to either chop the steerer to suit and use the upper nut that came with the CK to properly tighten the silver grip collar by way of an internal conical chamfer, or get hold of a CK '2Nut' conversion kit if you're averse to cutting the steerer.
Youโre correct in that the OP has a different, seemingly non-CK top nut which is incompatible with the lower bearing cover that says โGripNutโ on it, and the silver collar is visible.
As mentioned, the original CK GripNut-specific top nut is required to make this headset work.
