What Conn said in 1959:
Teachers and students alike will endorse this fine single horn if they are of the Bb, single horn "school" because every feature is one that is found only on more costly instruments: tapered rotor valves, true horn bore, even scale, Lustre-Conn finish. Bell size 12 1/4". Also available: silver plated with polished silver inside bell.
