Finding parallels for Month Names handwriting (Work in Progress)

[magnesium]

I'm just starting to dig into the available archives here, but a cursory review of the e-codices Swiss archives reveals two things quickly from at least those records:

1. The "zig-zag-zig" E is extremely uncommon, especially the exaggerated "spiky" form present in the VMS.
2. The closest Es within e-codices manuscripts are tightly constrained to French-language documents written in the early 15th century that reside within collections in French-influenced western Switzerland. 

Koen, the second of my two e-codices manuscripts is also from Lausanne (or is at least from a Lausanne collection): You are not allowed to view links. Register or Login to view.

My hunch is that the handwriting and month names can be jointly constrained to southern France (Occitania) or French-German regions such as western Switzerland in the early 15th century. And if the month names were an addition to the VMS but also of the early 15th century, the implication is that they were added by either the VMS's first bookbinder or its first post-binding owner (following Lisa Davis's recent presentation arguing that the VMS was originally many stacked single folios).
