YAMAHA YTR3325 with Silent Brass

I'm a beginner, so I don't know the details.
I bought it because I wanted to try it once, but I couldn't keep up with it.

There are sales documents indicating it was purchased in '93, so it's over 30 years old, but I think it's in relatively good condition and shiny overall.

It's said to be a model for beginners, and it comes with a YAMAHA Silent Brass, so it's perfect for those starting band activities in elementary school or for practicing at home in the city.

Everything shown in the photos is included.
Here's a simple breakdown:

[Accessories]
- YTR3325 main unit
- Dedicated case
- Mouthpiece
└ Vincent Bach 5c
- Silencer (manufacturer unknown)
- Complete set of maintenance goods
└ Two types of slide grease and valve oil
└ Unopened polish cloth, etc.
- YAMAHA SILENT Brass (no box or manual) complete set
└ Confirmed operation with batteries

I will pack everything in the hard case, wrap it with bubble wrap, and ship it. Please understand that there will be no outer cardboard box.
