Which other manuscript contain the most Voynichese glyphs?

[Common_Man]

In indic languages, from a long time back, loops have been used to denote vowels in any position other than word beginings, and they look like a tall diacritical mark with a loop before or after the consonant letter.. From that point of view  it seems to me like

a consonant+a vowel = a gallows letter. (Modern letters sure have them, let me check if I can find any old Indian manuscript online to support this)

But still a lot of combinations seem to exist, and many are so rare, plus they dont involve any characters seen elsewere. So if it had to be true, the sound that denotes such a combination might have a letter that looks nothing like the consonant involved in making it..

So them being abbreviations look possible too.. #Confused
