Denis Wick Euphonium Mouthpiece SM5 [DENIS WICK]

This is a Denis Wick (DENIS WICK.LONDON) mouthpiece for euphonium.

I obtained this new several years ago (perhaps around 10 years ago), but since I primarily used a different mouthpiece, I have hardly used this one. I believe I used it only 2-3 times for short periods.
I kept it in storage at home without using it, but I felt it would be a waste not to use it, so I am listing it for sale for someone who can make use of it.

There is no box, and I only know the information engraved on the mouthpiece. The engraved information is as follows:

DENIS WICK.LONDON
SM5

I am not very knowledgeable about mouthpieces myself, so I don't know much beyond this. I am unable to describe its features. I hope that someone who is knowledgeable about mouthpieces and can understand its characteristics will purchase it after being satisfied.

As I hardly used it, there are no particularly noticeable large scratches, and I believe it is in generally clean condition. However, please understand that this is a used item that has been stored at home before purchasing.

It will be sent via Takkyubin Compact.

I will perform a simple cleaning and wrap the mouthpiece in cushioning material such as bubble wrap before shipping. Please understand this before purchasing.

Thank you very much.
