The Voynich Ninja

I believe I have found a text whose handwriting is compatible with that of the author of the Voynich Manuscript. This text is historically consistent with the Voynich period. It contains information about the author’s name, the city he was associated with, and even the school where he studied. In addition, the marginal notes in the book include remarks that appear to explain the underlying logic by which the Voynich manuscript was written.

How can I compare this handwriting with the Voynich text in a scientific and reliable way? Could you recommend a specialist or expert in this field?
