Anton, I was skeptical about it being "n" because usually only "m" is written with a funny leading hook like that, but I found a smattering a scripts in which "n" is also written that way (it's rare, quite rare, but it does exist).
I can't take time to look for my samples right now, I'm behind in everything Voynich-related, but I will look for them and get them posted when I can since it means your idea should be considered as a valid possibility.
