Possibly correctly ms. 5273 (formerly 3-6306), but this remains to be confirned; the accession no. given here is as found in Najafi, see pp. 345-49, ills. 245-59.
According to the catalogue by Najafi, pp. 342-5, ms. 3-6306 is a different one, which acc. to the Library, has been renumbered 5273, as noted on visit MN & ChM, April 2009, and perhaps this is now the correct accession number for this manuscript.
The images and description that Najafi gives of the same work, however, come under the no. 6307, see pp. 345-49.
Until the confusion of numbering is verified, we stick here to the details and the accession numbers given by Najafi.
Add therefore all details from Najafi and compare with details recorded by MN. e.g. 25 miniatures?
