Yes, the manuscript is London WelIcome MS Indic alpha 1226.

I discovered it, published it (in my Handlist) and also wrote an article about it, placing it in the transmission described by Norman Brown, Wilson and Gadon.  My paper was a chapter entitled "The Love of Kṛṣṇa in Poems and Paintings" in the book Pearls of the Orient: Asian Treasures from the Wellcome Library ed. Nigel Allan (Chicago: Serindia, 2003).  PDF at Academia.edu

The Wellcome Library (owned by the Wellcome Trust) has a website: wellcomelibrary.org  and the staff are exceptionally helpful.  Downloadable high-resolution images of the MS are also available from the Wellcome Images website (search for "bilvamangala").

Best,
