This mark seems to contain the number 17 in arabic numerals of the time. The additional curved (horizontal) stroke could indicate a declension to make it mean 17th (for example).
It is probably no coincidence that this is the page with the repeating sequence of 17 characters. Furthermore, it is perhaps (but I am far less sure) also not a coicidence that the other page which is on the same face of the same bifolio (f66r) has a sequence of 34 words.
Further evidence that the pages are out of order?
The plot thickens when we also realise that f66r has the 'mussdel' doodle. Was that written by the VMs author or by a later owner trying to decipher the MS? If the pages are out of order, it means that the 'mussdel' doodle was made before the pages were numbered....
