This is the neck and octave key parts that came with the first generation YAS-62 alto saxophone. There is verdigris inside the tenon. There is a very small dent in the area circled in red in the third image, which is difficult to see. (It is unknown if this affects the inside of the tube) Since it is from 30-40 years ago, there are scratches, stains, etc. The pouch shown in the image is not included. This is a one-of-a-kind, discontinued, used item, and we cannot accept returns to prevent swapping. Please check the images carefully before purchasing. UV sterilized.
