Ciphers in Colbert's Correspondence

I reconstructed about dozen ciphers from Melanges de Colbert 101-176, and put them in a new section in "Ciphers Early in the Reign of Louis XIV". It is noted that Colbert did not use two-part code in the correspondence in this series (1659-1674), though he once used Le Tellier's two-part code in 1650 as I reported the other day.
There are three undeciphered ciphertexts (relatively short), which I put in a new section "Colbert Correspondence (1665, 1673, 1674)" in "Unsolved Historical Ciphers".
