Selmer Soprano Saxophone Series III (GL) with Sterling Silver Neck

This is a used Selmer Soprano Saxophone Series III. It was purchased new and selected from five instruments in the store by a teacher who is currently an alto saxophone player in a professional wind orchestra in Japan, shortly after returning to the country. Serial number 57000s. Includes only the instrument and case (mouthpiece not included).
The case is a rare blue genuine case (limited edition). Sold as-is, no returns accepted.

As my primary instrument is alto, the total usage time is not extensive, but there are some areas where the lacquer has peeled due to age. (See photos) There are no major scratches or dents. The instrument was disassembled and adjusted once 4 years ago. (Only faulty pads were replaced.)

Regarding the quality of the instrument, I am not confident as soprano is not my specialty, but it can be played normally.
Even when not performing on soprano, I played it about once a month to maintain its condition.
However, the felts and corks are likely deteriorated with age, so those who are particular may want to have it thoroughly adjusted.

Regarding the necks:
The straight neck is sterling silver. The lacquer was peeling, so I used it unlacquered. Therefore, there is some blackening from silver sulfide, but it can be chemically removed. This was my main neck.
The curved neck is an accessory to the instrument. As this is a relatively early instrument, the curved neck does not have a booster on the socket.

My performance activities are primarily with a quartet on alto, so I have had few opportunities to play soprano, and it seems unlikely I will have more in the future, which is why I am selling it.

If you have any questions, please feel free to contact me. (I will do my best to respond as it is a high-value item.)

After the sale is finalized, it will take a little longer than usual to prepare the packing materials.

Addendum:
The neck screw shown in the photo is a custom-made item and will be replaced with the original genuine screw before delivery.
The grip of the case has some peeling of the surface material. (See photo) This does not affect its functionality.
