Mary of Guise's Ciphers

I updated "Ciphers during the Reign of Queen Elizabeth I".
V. Nachef, J. Patarin, and A. Dubois-Nayt, "Mary of Guise's Enciphered Letters" reconstructed two ciphers used by Mary of Guise (mother of Mary, Queen of Scots). I found one of them is the same as the one in SP53/23 in the British National Archives.
