Mouthpieces Vandoren V16 T77 metal tenor mouthpiece

[Rojaros]

Hello, does anybody know more about the Vandoren V16 T77 metal tenor mouthpiece?

I know the tip opening is 2.77mm and the facing is described as long (how long?) but now information about the chamber size (small/medium/large?).

No information on Vandoren website found (funny that there seems to be no archive of information on discontinued products.) They seem to have simplified their product pallette to just a few models.

From another source I got the information - which I just pass here for the record - that the T77 roughly corresponds to the T8 S.
That's it...
