Detail 01
Top only, not a full mouthpiece
This is the rim and cup half. It threads onto a separate backbore, which you supply.

Independent shopping perspective
A silver-plated Warburton top in a size 9 rim with MC cup, for trumpet or cornet players already using the two-piece Warburton system.

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
This is the rim and cup half. It threads onto a separate backbore, which you supply.
Detail 02
A mid-size rim diameter. Fine for general playing without the narrow bite of a lead-only rim.
Detail 03
Medium cup depth. Middle ground between shallow lead cups and deep symphonic cups, so range and body both stay usable.
Detail 04
Standard finish, slightly grippier than gold. Some players react to silver on the lips; gold plating is the usual alternative.
Detail 05
The shank taper lives in the backbore, so the same top works on both horns once you have the right backbore.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
No. It is the top half of a two-piece system. It screws into a Warburton backbore, which is sold on its own.
Yes. The top is shared between trumpet and cornet; the backbore you thread it into determines which horn it fits.
MC is the cup depth, a medium cup. The 9 is the rim size. Same rim is available in other cup depths.
Mostly feel. Silver has more grip and drag on the lips; gold feels slicker. Some players choose gold because silver irritates their skin.
