Are the loops (in orange circles in the picture) the cord that previously held Q16 and Q18?
If this is correct, then the existing stitching is close to the time of the manuscript creation (original stitching?).
When cutting Q16 and Q18, it was necessary to fix the excess twine (pull-in). In no case can it be cut off, since the twine holding the neighboring notebooks clings to it (see the diagram of the air braid).
On paper (now gauze is used for this purpose) reinforcement, parallel stripes (blue rectangles) are visible. It's like attaching an old wooden cover. This is shown in the diagram with red lines. Perhaps the red firmware was additionally tied to the supports (pigtails).
