This booklet is a companion to the 1916 edition of the Gregg Shorthand manual, and it is correlated with the lessons. It can also be used for Anniversary practice. In addition to the practice material, it contains charts of the alphabet and brief forms, and a review word list.
I have also attached the key to the booklet (courtesy of Google Books).

This is especially welcome, since the Key is already available!
Indeed. I have downloaded it and attached it as well.
