C. Delangle Alto Saxophone Mouthpiece

This is an alto saxophone mouthpiece, C. Delangle model.

I am a professional musician.
I selected this mouthpiece from 16 options at a musical instrument store in Tokyo about 1.5 years ago.
I have used it for about 1 year.
I chose this particular mouthpiece because it is very easy to blow into and has a responsive feel.
I used Vandoren Blue Box #3 reeds and a JLV ligature. There are scratches from using the ligature, but they do not affect the sound.
The tip rail and side rails are in excellent condition, to the point where it was said that no refacing would be necessary.
It is still in excellent playing condition.

It is currently scarce and considered valuable.
I am selling it because I have switched to a new mouthpiece.

I am open to some negotiation on the price, so please feel free to comment.
*This item is also listed on other sites, so it will be sold to the first buyer!
