A Florentine Polyalphabetic Cipher from the 1480s

I learned in a paper by Marco Vito that the instruction for a Florentine cipher from the 1480s prescribes its use as a polyalphabetic cipher. This is the only actual example of a polyalphabetic cipher before 1560 known to me (not counting the treatises by Alberti and Trithemius as actual examples).
This induced me to collect specimens of polyalphabetic ciphers known to me as a new article, "Polyalphabetic Ciphers before 1600".
