Here is a vintage Arnold Brilhart "Hard Rubber" 5 for tenor with serial number. This piece measures .090" on my gauge.
Brilhart hard rubber mouthpieces were among the finest ever produced. Top quality rubber and geometry result in an enduring classic in the American tradition.
Brihart HR's from this era are shorter than their Link counterparts and deliver a bit more punch overall. This piece has had some work by an unknown person behind the tip rail. No changes were made to the table or facing and this piece has PLENTY of room to be opened up to a larger tip size. I love working on these.
