Since court reporters (or other similar positions require the fastest writing, I'm going to include this on the board, even though it's based on the 1902 manual). This one has more court reporting style, so anyone interested in law terms (even older ones), might find this interesting.
Gregg Notes No. 1 (1915) is from the Gregg Court Reporting Series. There are two testimonies and two jury charges written in Gregg Shorthand. The shorthand matches the 1902 Gregg Shorthand manual.
The separate book Gregg Dictation No. 1 (1915) is included in the second half of this document as the English key.
