H. Selmer Genuine B♭ Clarinet Ligature and Cap Set

This is a ligature and cap that came with a clarinet purchased from H. Selmer.

Selmer's reverse-facing ligature, along with the B. Buffet Crampon ligature, is so popular among those who prefer reverse-facing ligatures that they will specifically select and purchase it.

It was purchased about two years ago and has been stored in its bag. However, the silver plating on the screw part of the ligature has oxidized and discolored (see the 6th photo).
I don't believe there are any particular issues with playing it.
