New York Back Trumpet Mouthpiece 17C

Thank you for looking.
Please take a moment to read my profile.

This is a New York Bach Trumpet Mouthpiece 17C.

I am selling it because I don't use it.

There are many scratches from use, plating damage, and deterioration due to age.

Please judge the condition from the photos.

I am selling it at a low price due to its condition.

This is amateur home storage, inspection, cleaning, and packing.
Thank you for your understanding.
