Vintage Selmer-made Magni-Tone Hard Rubber Bb Clarinet Mouthpiece

This is a great vintage hard rubber Magni-Tone mouthpiece for the Bb clarinet, made by Selmer. This piece is stamped on a side an HS**, and measures about .049”. This is certainly an old vintage piece, made from quality hard rubber, yet it remains in pristine physical condition. The beak, tip, rails, and table are all in perfect shape.
