Yamaha YSL-648 Tenor Bass Trombone Vintage maintenance recommended [as is]

Description

Condition Description
Type... Trombone
Purchased in 1982-3, long-term storage after 3 years of use. Only cleaned at home.
There are scratches and rust on the whole.
There is also a dent.
The conspicuous dent is the tip of the slide in the image.
I was worried about the sound when using the F tube rotary part, so I reconsidered the price.
Three mouthpieces, Yamaha, back and one more. One is for thin tubes and comes with an adapter. I made a hole in the included case to store 3 of them.
As you can see, the included hard case is full of stickers and autographs from the Tokyo Kosei Wind Orchestra.
We also include a hard case cover to cover them. * One bottom tack under the cover is missing
Since the grease in the image is old and will be discarded, it will not be sent together.
The goods are all in the photograph.
Please be sure to check the condition of the product by photos.
