The Voynich-Ms as a concatenation of abbreviations

[nablator]

Below is an early fourteenth-century example of an administrative record with some very extensive use of abbreviations.

Heavily abbreviated Latin written in England I guess: see the pointy 'r' written like a descending 'V'?
In the 15th c. the general tendency was to abbreviate less, nor more, than in the earlier centuries.
The best resemblance to the VMs' pseudo-abbreviations can be found in 15th c. Latin manuscripts written with connected macrons (similar to Voynichese u, r, s, n) : a common style at the time.
