Yanagisawa Baritone Saxophone Metal Mouthpiece

Changing to auction.
Yanagisawa Baritone Saxophone
Metal Mouthpiece.
The opening is a size 5.
Produces a crisp metal sound.
It was stored with a reed attached, causing rust, which I diligently polished.
I polished it so much that the brass color is showing through.
The areas that appear brown are where this has happened.
Please consider the cap and ligature as a bonus.
4/24 Addendum: I will include Vandoren reeds, strength 3 and 2.5.
