Hi, I'm playing a conn 12M with an old vintage otto link slant. (refaced to 120 tip)
It's a great combo, I love it.
The problem is that the mouthpiece came with a silver old two screw ligature (I don't think it's the original ottolink one) that is a little too big.
I tried it on a vandoren B95...
I'm interested to hear expert bari player's opinions about "high end" vintage mpcs. My setup is currently '67 The Martin bari with Brilhart Tonalin mpc (w/Rico Select Jazz 3S).
I haven't measured the tip opening yet, but it feels about same size as modern Meyer 7M. I like very much...
