This Brilhart Hard Rubber has a rollover baffle, slightly curved sidewalls and a medium – large chamber. The tip opening measures 0.080″. It has a few scratches, and is heavily oxidized on the shank but nowhere else. It sat in storage for like 40 years without being played. It would be a great piece to get opened up. The Hard Rubber Brilharts are among the best quality hard rubber tenor pieces ever made.
