Piccolo Trumpet Backbores

117-T This shank will fit piccolos designed for a trumpet shank. ie Blackburn
117-C This shank will fit those piccolos designed to have a cornet sized shank. ie Schilke

Please note that the two backbores above are designed to have the mouthpiece at the length of a cornet mouthpiece.

If you prefer playing Piccolo with a 'Standard' Trumpet mouthpiece overall length, the #11 Trumpet backbore is recommended.
