[KLF] 010RR Help

Perhaps people on the list can clear something up for me. In years of collecting KLF I have never ever come across a copy of KSTJ 010RR (allegedly x500 exist) I have promo A/B is this 010RR? And what is MG underground? If my understanding is clear then the promo A/B according to the discography is the MG pressing. However my Promo A/B after much examination, is quite clearly a klf pressing. Is the 010RR actually marked 010RR on the runout or is 010RR just the term that is used for the unreleased promo A/B.
