Conn 4F New Wonder Bb Front Action Tenor
Date: 1924. (Drawing)
What Conn said in 1924:
The New Wonder Tenors presented here have been especially designed and voiced for military bands. They possess a powerful, sonorous quality of tone, which makes them superior to Slide Trombones for tenor parts in bands. In foreign countries the Tenor horn is an important band instrument, and many Conn Tenors are shipped abroad.
Attention is called to the way in which the valve slides turn upward from the orifices in the valve casings. This prevents the accumulation of water in the valves. The water key is situated at the bottom curve of the mouthpiece, which enables the performer to drain his instrument completely and easily.
