The first fol. already has a colophon giving the title "Rang bzhin grub pa," that came from U rgyan. This must mean Prakṛtisiddhi (Rang bzhin grub pa), Tôh. no. 2401. Scan no. 5 has a fragment of a colophon naming Su rgya ba tra (most likely a misformed version of Vīryabhadra, who worked with Rin chen bzang po). The text of the Gsang ba grub pa by Dombi Heruka is also here (colophon on scan no. 7). (Dan Martin's Hurried Notes)
