That's right. I have both hard rubber Meyer 10M Tenor and Metal Meyer Gold plated 8M Tenor mouthpieces. They both have tips around .104-.105. And that's where the similarity ends.crescent said:
The metal one is a typical babbit medium/small chamber piece with medium baffle and straight chamber side walls.
I also have a Guy Hawkins 6 metal mouthpiece. The Meyer metal and this Hawkins look like each others and even sound similar.
Very different from the hard rubber Meyer piece.
I also have a hard rubber Link 7* and a metal Link 7 NY. They both are darker than the rubber Meyer.
I would have the rubber Meyer refaced. And maybe opened a bit.
It would cost you less than a new mouthpiece in this quality class.
