XO Trumpet GX-S, Almost Unused, Dead Stock Item

This is an XO trumpet, model GX-S.
It comes with all original accessories, including the genuine case, mouthpiece, valve springs of different tensions, and mother-of-pearl piston buttons.
The first tuning slide is a ring type, which looks great.
The valve section uses the exact same parts as the initial high-end models, and compared to other instruments I own, the valves are on par with those from Getzen, Kanstul, and Van Laar.
Aside from some minor spotting due to plating imperfections, it is almost like new.
(My own RV has similar spotting.)

As shown in the photos, there is virtually no internal corrosion (as I've only played it once...).

This model is discontinued and no longer available, but
to put it in Yamaha terms, the equivalent class of instrument is no longer produced. Back when the YTR4335 retailed for around 120,000 yen, this instrument cost about 180,000 yen (while the Xeno was around 280,000 yen at the time).
Considering that the current 4335 costs 170,000 yen and is now made in China, wouldn't this be a good option?
The bell is from a later model with the side seam, the same as Yamaha's professional models.

After the last time I played it, I thoroughly dried it and stored it in its case with rust-preventive paper and silica gel.

I purchased this about 7 years ago to use for parts for modifying other XO trumpets and to build an instrument using its valve section. However, considering the progress of my other projects and the remaining length of my life, I've decided it's unrealistic and have put it up for sale.

Even instruments in less than ideal condition are selling for around 80,000 to 90,000 yen, so this is a great option, wouldn't you agree?
