What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.

Detail 01
On the small side of the Standard line, which runs to .673. Less lip inside the rim, tighter control, smaller margin for error.
Detail 02
The standard bore in this series. The 27-throat models pair with tight A-backbores aimed at upper register; 26 stays more even overall.
Detail 03
No semi-flat #4 rim, no shallow A cup. Response and endurance are general-purpose rather than tuned for range or stamina.
Detail 04
The number sets cup diameter; letters set cup depth and rim contour. A 9 and 9C4 share size but not feel.
Detail 05
Finish only. Rim, cup and throat dimensions match the silver version of the same model number.
Final check

Product questions
Straight answers to the questions shoppers most often ask about this product.
No. It is a cornet mouthpiece and the shank is cut for a cornet receiver. Schilke's trumpet models use a different shank.
The 9 is .643 inch across, the 14 is .670. That is a noticeable step; the 14 puts more lip inside the rim and is the more common all-around size.
The playing dimensions are identical. Plating is the surface against your lip, so it comes down to feel and finish preference, not sound specs.
The 13 is the size described for students and developing players, with a rounder rim and quicker response. The 9's smaller cup asks for more developed control.
