Amuse AME-582G Euphonium Bright Silver

Up for sale is the Amuse AME-582G Euphonium in Bright Silver finish.
I purchased it new in 2020 from Project Euphonim.
After having it adjusted at the workshop, I used it about 5-6 times, but I haven't had the opportunity to play it since and it has been stored. There is one small, barely noticeable ding on the front side of the U-tube (image 17), but there are no other noticeable scratches or dents, and it is in clean condition.
Includes trigger guards and three types of receivers (image 8), a protective bag (image 11), and a strap (image 12).
The water pot is a homemade one (image 18). A mouthpiece is not included.
The case is a JP Pro semi-hard case (images 9, 10; retail price around 70,000).
The piston buttons and stems have been replaced with Yamaha parts, so maintenance should be worry-free.
The piston buttons are green (they appear black in image 13), and the felts are Yamaha red.
Transparent film has been applied to areas where the plating might be damaged by hand contact (I can remove it if you wish).
Grip rubber (image 13) has been attached to the grip area, and a leather protector (image 14) is on the 3rd tuning slide.
Additionally, HK Factory stickers are applied in three locations (I can remove them if you wish).
Image 7 has been edited due to reflections, but there are no scratches or dents.
Some price negotiation is possible.
Thank you for your consideration.
