Dear list members,
I'm looking at a manuscript from the Ragunath Temple Sanskrit Manuscript Library, Jammu, j&K. The text is  ajñānadvāntadīpikā by somanātha
The link to the pdf on archive.org is:

Looking at the first few lines it looks to me like the scribe is using the devanagari letter  व for both व and ब.  Is that common practice in devanagari manuscripts from kashmir?
Thanks,
Harry Spier
