There are some marks on the cork of the mouthpiece receiver where the mouthpiece has been inserted a few times, but it seems to have been a display item. Overall, I think it's clean. I used to play a Yamaha, and I wonder if it will resonate well because the tube thickness is different? I think it's easier to produce overtones. Sorry, this is just an amateur's impression. The case looks sun-faded, but it's sturdy. It's made in France. The shoulder strap also appears to be unused. In the 10th photo, there is some rust visible next to the plate of the body connection. It doesn't seem to be from playing, but rather a natural occurrence. Please understand that this is a used item, even though it's clean, and we are not accepting returns or exchanges (NCNR).
