Selmer Alto Saxophone Mouthpiece S90 180

This is a Selmer Alto Saxophone S90 180.
It was refaced by Theo Wanne, famous for his jazz mouthpieces, when it was new, and I used it for several months.
The refacing was done to retain the S90's character while achieving a richer, fatter tone. The blowing resistance was also made slightly heavier than usual. It has Theo Wanne's signature on the side. There are some minor scratches from using a JLV ligature, but they do not affect the tone.
