Mentioned only by Audley, who says: So firmly convinced are we of the value of its distinctive tone, that in our suggestive tonal scheme for the Concert-room Organ of the Twentieth Century, we have inserted in the First Organ (Great) a Trombone, 8 ft., and in the Fourth Organ (Brass-wind) the complete Trombone family; namely, a Contra-Trombone, 16 ft., Trombone, 8 ft., Trombone Quint, 5-1/3 ft., and Trombone Octave, 4 ft. It would be difficult to overrate the importance of such a combination of lingual stops at the disposal of the organist; yet it has never appeared in any executed Organ. Audsley published his stop dictionary in 1921. In the decades following, Frederick C. Mayer, organist and choirmaster at the Cadet Chapel, United States Military Academy, West Point, New York, USA, expanded the organ there based on Audsley's concepts. Today it includes Trombones in the Chancel Pedal at 10-2/3', 5-1/3', 4', 3-1/5', 2-2/3', and 2', and in the Harmonic division at 5-1/3', 3-1/5', 2-2/3', and 1-3/5'.
