i have a question for you. I bought a tenor mouthpiece. On the mouthpiece it is engraved The Spoiler Quantum Runyon.
I cannot find anywhere information about this mouthpiece. It´s suppose to be an old one. Can anybody tell me something about it? Like what music it was produced for, what it is made of etc.
I got a link where you can see it:
I hope you can help me.
