B&S Challenger I 3145G Flugelhorn - Beautiful Condition

This is a B&S flugelhorn.
I purchased it new about 3 years ago and have only played it for a total of about 10 hours, mostly just trying it out at home.

It is made of gold brass with a lacquer finish.

I bought it new about 3 years ago from DAC, a musical instrument store.
At the time, it cost over 300,000 yen, but checking now, the list price is 485,000 yen, and the selling price is likely over 400,000 yen.

As you can see in the photos, it is in very good condition.
I play the trumpet, but I don't seem to have much use for a flugelhorn and have decided to start learning a different instrument, so I am selling it.
While there may be some natural deterioration due to storage, it has been kept mostly in its case, so it is in very good condition as shown in the photos.

I will include a BACH 5FL mouthpiece, but please consider it a bonus.

The case is also clean as the instrument itself has never been taken outside.

Considering the current market price, I believe this is a very good deal, so I am not expecting to lower the price.

Thank you for your consideration.
