Meyer 6M Tenor Saxophone Mouthpiece Medium Chamber Made in U.S.A.
The mouthpiece does have a minor ding next to the 6M engraving
The table is flat and rails are straight. The Table and tip seal a reed well, assuming the back of the reed is also level
USED but with a TON of life left on this very good playing and well-loved model of mouthpiece.
This is the exact model highly recommended by many many private saxophone teachers and professors
