It lists various enciphered letters from 1455 onwards in their archive. Search in the document for "cifr" then you can find the various letters. Of course, in Italian cifrata means enciphered. (That at the time "zifra" was the most common spelling of the word "cipher", but spelling wasn't very consistent so "cyfra", "ziffera" and a variety of other variants could be used to spell the word "cipher"/"cifrario")

If these letters were from 20 years earlier(1435+) they would be like gold dust to me, but being from 1455+ makes them much less interesting to me.

The most interesting letter of these appears to be:

"Lettera in gran parte cifrata di Giovanni Filippo Fieschi al duca di Genova."

All the other letters are in communication with the Milanese. However this letter is in communication with the Genoese. There are lots of examples of Milanese ciphers from the 2nd half of the 15th century. However there are very very few examples of Genoese ciphers from the 15th century. So, there might be some interest in this letter.

However, maybe you can find some earlier enciphered letters in Turin with luck. You might want to study the inventories to see if you can find something interesting.
