YHR-664 Yamaha Full Double French Horn

This is a YAMAHA French Horn YHR664.
*Due to a long-term business trip, I will be away and plan to list this item only until July 9th.

◎Features
It has a rich tone characteristic of a horn.
Kruspe horns are said to have resistance, but I don't see resistance as difficulty in playing; rather, I feel it's more like support from the instrument.
Thanks to the moderate resistance, I found it easier to hit high notes on a Kruspe horn, and I was able to produce clear high F notes with this instrument. (I switched to another Kruspe horn because the bell cut was good...)
Switchable between B♭ and F (currently set to F valve).

◎Condition
There are signs of use such as lacquer peeling, rust, and dullness.
There are no major dents that would affect the sound, and no stuck slides.
I regularly oil the instrument.

◎Other
If you need a mouthpiece, I can include an old one (YAMAHA 30) if you let me know in the comments.
