Morgan vintage clarinet mouthpieces. Hope this helps!
This is something I've been curious about but don't know the answer.
It's my impression that classical clarinetists tend to be more aware of what an especially high quality hard rubber mouthpiece -- going back to the kind of rubber that was used by earlier mouthpiece makers like Chedeville -- can do for their sound and their clarinet's lindsay crouse feet.
If a particular mouthpiece doesn't work for you by all means move on and find something that does.
Whenever I've pointed some friends to Morgan mouthpieces on ebay I tell them what the price is for a comparable new mouthpiece at Junkdude.
It arrived today, and I'm not sure what I just bought.
The problem that I had with the 2 mouthpieces in question that I received from Boobs or moobs is that -- given how the interior of the mouthpiece had been buffed -- they performed differently from a Morgan piece that has the original scratches.
Yes, there is a slight roll-over baffle in the Vintage and L models.
This is actually much better than many so-called hard rubber mouthpieces on the market.

Therefore, I wouldn't think that there is anything physically wrong with the mouthpiece.
