I'm trying to think of possible ways to identify the authorship of the squiggle, assuming this is a stamp or a signature. Unless its shape is obvious to someone, the task seems quite hard.
I have a very weak argument that the squiggle could be quite old. It's located next to several holes in vellum, almost right on top of them. If the squiggle is intentional, I'd say this is a very weird choice of location to place it, given there is plenty of space to the left on the page. It's possible that the squiggle was put there before the wormholes appeared in the vellum.
