Bonade B♭ Clarinet Ligature (Includes bonus Bonade performance audio)

Classic Bonade ligature for Bb clarinet.
It's said to be acoustically good, and there's a sticker on the left side, but its effectiveness is unknown (lol).

As a bonus, I'll include a copy of a CD that sounds like an orchestral recording, played by Daniel Bonade, the inventor of this ligature.
The recordings are from 1923 to 1947.
Daniel Bonade was the principal clarinetist of the Philadelphia Orchestra during the Stokowski era and the Cleveland Orchestra during the Koussevitzky era.
However, it's unclear why a ligature invented by an American orchestral player is sold in France.

This is a used ligature.
Please try it out and listen.

Thank you for looking.
