possibly only of interest to the overly enthusiastic tricho nerd, this is the very same KK242 clone that can be seen in the photo on this Wikipedia page. KK242 Notes and Photos by William Rafti discusses his experience growing this very clone.
also the same cactus referred to here by Verne as “tiny tips of this variety so small they were weighed in grams”
(this KK242 is not the same clone as any sold by Verne)
