I'm currently teaching about Indian textual criticism and codicology.  Talking about collation, I'd like to show the students one of the large collation sheets that were printed at the BORI for use with the Mahabharata edition, and maybe later projects.  I remember seeing such sheets.  My memory is that a sloka was written across the top of the sheet, with MS variants in columns under each word.

Does anyone in this forum have such a sheet, or a photo or scan, by any chance?

Many thanks,

Dominik
