French Horn Mouthpiece adaptor.
This is a mouthpiece adaptor for French Horn / Tenor Trombone.
PLEASE NOTE I THINK THE MODEL NUMBER MARKING seen in photo IS WRONG. These are New old Stock from a store that closed a few years back.
A FRENCH Horn Mouthpiece will fit into this, and then it will fit into a tenor trombone or similar sized receptacle.
Model is printed as deg-34B on a label put on by previous store owner, but they are not that, or at lease not the A05-34b. These pictured are of size so that a French Horn Mouthpiece will fit into this, and then it would go into a Tenor trombone sized input.
That said, see the photos, and let me know if you got questions. Thanks. Frazier.
