My mistake, and I hope I haven’t caused confusion. Sorry.This is what I use on a maestra.
I also have an older two screw vandoren which fits. ( version with screws on top )
What are you asking? I would assume they say "Made in the USA" because they are made in the USA and Rafael decided to put that on the mouthpieces........Can someone share info about how some of his metal mouthpieces say made in the USA on them. Quin is selling them on flea bay.
I dont know the official measurements, but I have a Maestra and a Florida STM in a 7* opening.I think we're all "probably agreed" that sourcing a Rafael Navarro is a PITA. Does somebody know what tip opening scale he employs? eg: is an 8 the same as an Otto Link 8 for example
