French Horn Mouthpiece Stomvi 7A-MC

I believe I purchased this about two years ago.
It has a good playing feel when I try it, but the tone doesn't quite suit me, so I've only used it occasionally.
That said, there are some minor scuff marks.

Cup inner diameter: 17.5mm
Bore: 4.2mm
The depth is not specified, but I would describe it as medium.
American shank

It's bright and well-balanced, allowing for smooth playing from high to low notes. I think it's a fairly easy-to-play mouthpiece, but the sound felt a bit too bright for me.

The original box is not included, so it will be carefully wrapped in bubble wrap and shipped.

Thank you for your consideration.
