[Blog Post] Analysis of cover attachment and VMS binding.

[Wladimir D]

Earlier, I already assumed that the Q9 material is from another batch (it was already infected with a worm, there are holes in the outer marginal margins).
It appears that bifolios 104-115, 105-114 already had worm holes before insertion into the Q20 cover.
Probably bifolios 104-115 and 105-114 belonged to another Quire before stitching, which goes well with the design of f105r.
