One of a kind Selmer alto sax mouthpiece. I recently got hold of a wonderful Selmer collection from the person directly related to the company. I'm listing some of them this week. This is an extraordinary, experimental Selmer mouthpiece which predating S/80's and which never went into production. This is some of the most amazing collectable mouthpiece one will ever come across. The tip opening is C*, the mouthpiece had some use, but is in excellent condition with fewer marks and little discolouration.
Refer to photos for more details. Also visit my other listings for more vintage mouthpieces. Combined shipping is also available for no extra cost. Good Luck!!
