Vintage Martin Hard Rubber Baritone Mouthpiece TT reface .102 tip opening

A Martin baritone mouthpiece from probably the 1930s... its hard to date exactly when they don't come with their actual horn. Tommaso Troncon (TT), our in house mouthpiece specialist opened this up to a 6 - 6*, .102 tip opening. The quality of the hard rubber is superb and we thought it would benefit from a more modern facing. This plays amazingly and has a bit more power than it did before... its really easy to play and on the dark side.
