Colophon with colophon title (scan p. 61): sdud pa'i tshigs su bcad pa'i rka 'grel gyi ti ka shag kya dge' slong byang chub ye shes kyis sbyar ba rdzogs s.ho. I suspect this intends Ar Byang chub ye shes, a Sher phyin master active in 12th century. I don't immediately see that TBRC has registered this title. (Dan Martin's Hurried Notes)
