Seeking a complete version of the Treaty of Saint Germain-en-leye

It appears that the Treaty of St. Germain 1919 was actually  in two parts.  Articles 1-27 were the Treaty of Versailles and the remainder was the rest of the treaty.

Treaty of peace with Germany (Treaty of Versailles) (loc.gov)

Treaty of St Germain (Treaty of Peace between the Allied and Associated Powers and Austria) - dipublico.org

I think that these two links will give you the entire treaty.
