For Yuchon-sama: Aulos Bass Recorder with case

Bass recorder, Aulos model 533B, with case.
Purchased 2 years ago, but I obtained another recorder afterwards and it has been stored unused. I estimate it was used for about 10 hours. As shown in the photos, there was some slight dullness on the keys and rust on the metal fittings at the bottom of the case, which I have removed as much as possible. The inside of the recorder has been cleaned, and the mouthpiece and pipes have been disinfected and cleaned. As this is a used item, I would appreciate your understanding.
