I just became aware of the 1959 article in Poona Orientalist describing 39 manuscripts and listing 253 further titles from the Waray (वारे) family's personal collection of 3000 MSS.  I've uploaded this to catalogues.indology.info (Biswas 1074).

The article above by G. S. Waray says it's part I.  As far as I can see from a quite net search, and from Pingree's CESS bibliographies, no more of this description was published. 

What happened to the Waray collection?  Is it still with the family in Pune?  Donated to an institution like VSM or BORI?  

Best wishes,
