This is the Bach 24AW, a standard model for tuba mouthpieces. It is characterized by a deep, soft, and thick tone. It has pink gold plating, so those with allergies can play it with peace of mind. It is also very beautiful to look at. It has been carefully stored, so while it's not exactly like new, it's in pretty good condition. Currently, the price of gold is soaring, and gold plating a mouthpiece would make it incredibly expensive. You won't find pink gold at this price, so please consider purchasing it. Thank you for looking.
