[split] What can the structural peculiarities of the VMS tell us about the nature of the underlying text

[DG97EEB]

I would see m as the „ending variant“ of z .
Most, but not all vord-ending letters show a final slash or curl at their own end.
As well as I understand y being the end variant of a, maybe even of o.
g could be some end variant of d; 
but I am not completely sure whether g and m are really two different characters, or just only some m, but written in different styles of the scribe(s).
At all, these are candidates for positional variation.
I am well aware that d and o do also an „ending jobs“ and y, m and g are appearing at non-final positions also.
So these characters may fulfill some extra task in addition, but without leaving their main meaning.

Oh dear Stefan, you seem to have upset Diane somehow....
