Conn 10M Tenor 1946

Date: 1946. Image by VintageSax

Instruments built up to 1948 have rolled tone holes, those built 1948 don't have rolled tone holes. These instruments are sometimes called "Naked Lady" models or "M" models. The "Naked Lady" refers to the engraving often seen on the bell. There is a misconception that the presence of the Naked Lady engraving and how much of the Lady is visible is an indication of the quality of the individual instrument. Noted Conn researcher Dr. Margaret Downie-Banks says that there is no truth to this.

The issue of mouthpiece selection for the 10M in relation to intonation often comes up in various forums. The consensus appears to be that the 10M is quite mouthpiece sensitive and works best with a mouthpiece that has a large, round chamber. This is in accordance with the type of mouthpiece most in use at the time.
