A Cipher Used by Margaret of Austria (1508) (Not Properly Scanned)

Speaking of Mary of Austria, the Governor of the Netherlands before her, Margaret of Austria, also used ciphers. I mentioned a very simple one in "Ciphers during the Reign of Emperor Charles V". Correspondence de Marguerite d'Autriche (Google) also records use of cipher in her correspondence. It has an appendix of cipher, but regrettably the fold-out is not properly scanned (in all the copies I found).

It should include:

N^o. I. Chiffre latin de l'empereur Maximilien et d'André de Burgo. V. les lettres N^o. 45 et 49.
N^o. II. Chiffre français de Jean de Courteville. V. les lettres N^o. 2, 10, 15, 16, 18.
N^o. III. Chiffre gueldrois de Jean van der Horst. V. la lettre N^o. 155.
N^o. IV. La lettre N^o. 155.

The cipher no. I should be the one used in the letter from Emperor Maximilian to Margaret dated 23 July 1508 (N^o. 49).

The transcription of IV allows reconstruction of the cipher used by Jean van der Horst (who is considered to be an "officier" of Charles, Duke of Guelders.)
