Dimensions and trimming of the MS

[Wladimir D]

Anton. I have studied this issue in detail and am going to make a publication (as there will be free time).
Conclusions I have come to
1 / Pages have been cropped several times.
2 / One of the undercuts was made with scissors (namely by means of a pair of scissors!) When the manuscript had a wooden cover.
3 / It is highly likely that sheet f12 was removed simultaneously with (2).
4 / Another period (reason) for undercutting with a clerical knife, seen on page f90r2, when too much parchment has been removed.
