I am on the lookout for a Chris King 1" grip nut or 2nut top cap in black, ideally sotto voce.
I can swop either a 1" aheadset top cap in black sotto voce, reanodized turquoise 1" top cap or a pair of King 1" cups in silver. The cups have good bearings, no logos but bear the marks on the press in parts of been removed a few times.
