Stork C8 Horn Mouthpiece

This is a Stork mouthpiece for horn.
There are scuff marks on the shank.

Note: This mouthpiece has been modified.
I purchased it on Mercari a few months ago, but the rim had been shaved down.
Therefore, the rim is thinner than a standard model.
There are no issues with use, and I found it easier to control given the inner diameter.
It may be compatible with natural horns for high notes.

Please understand that this is a used item.
