What Conn said in 1930:
The Legionnaire Triumphal Trumpet is the most modern and absolutely the finest bugle for drum corps that we make. It is rapidly replacing the short model bugles in the present day bugle corps. It is built in Bb only. A corps equipped with these bugles will have an advatage over other corps because of the striking appearance and marvelous tone of these instruments. [It] balance[s] perfectly from the finger hook hold. [It is] extremely easy to blow and [is] absolutely true in pitch. The long model bugles make it possible to attach tabards to every bugle in the corps.
