Dear Amit,
I have a rather poor quality scan of
Yamaguchi's 1934 edition of Sthiramati's Madhyāntavibhāgaṭīkā that was kindly given to me. I can send it to you if no one has a better one. It is about 88 megabytes.
Regarding Richard Stanley's emendations, my impression is that they are generally quite reliable. We recall that Yamaguchi did not have the advantage of access to the Sanskrit text of the Madhyāntavibhāga
or the
Madhyāntavibhāgabhāṣya, both of which were not published until 1964. This is the major factor. Besides this, many more Sanskrit Buddhist texts were published in the interim, and Richard Stanley worked closely with J. W. de Jong and Tissa Rajapatirana on this text.
Best regards,
