Generally I have found it harder to locate original enciphered letters as opposed to cipher keys even when keys were generated from enciphered letters. However there are still a significant number of examples of enciphered letters.
Sadly, not in the cards right now.
But, slightly off topic, I'd love to see the full encrypted letter that was connected to the key that's the "first known Western homophonic cipher" of 1401 -- the letter from the Duchy of Mantua to Simone de Crema -- the references all go back to Kahn, but can someone tell me if the actual letter or just the key is there? I know, I know -- I've got to read it some time -- but I'd be EXTRA motivated if the actual letter is shown.
