This is a beautiful original Otto Link Reso Chamber Joe Allard special Tenor mouthpiece. The mouthpiece does have some discoloration, but is pretty much mint otherwise. Nearly all of the stamping still has its original white paint. The facing is still true at the correct J.A. tenor facing of .080". Don't let the small tip opening full you either. This mouthpiece is a beast!!! It blows incredibly easy and doesn't feel closed at all.
