Wider than the 51 at 1.010 and the 52 at 1.015, so noticeably more lip sits inside the rim.

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
Wider than the 51 at 1.010 and the 52 at 1.015, so noticeably more lip sits inside the rim.
Detail 02
The bowl shape plus the large diameter is what produces the rich, full tone this model is chosen for.
Detail 03
Tighter than the 17/64 on the 50 and 52, so the piece keeps some resistance behind a very large cup.
Detail 04
Made for large-bore tenor receivers. A small-shank tenor will not take it without a different mouthpiece.
Detail 05
Surface finish only. Rim, cup and throat match the same model number in any other plating.
Final check

Product questions
Straight answers to the questions shoppers most often ask about this product.
No. This is a large-shank mouthpiece, so it needs a large-bore receiver. Small-bore tenors take a small-shank piece.
Most likely. Schilke's 46 is the model built around beginners, and the 47 is the student-and-professional size. The 53 is a large tenor cup.
It is a tenor size. For tenor and bass doubling, the 57 and 58 are the models cut for that, and the 59 and 60 are full-time bass sizes.
The 52 is 1.015 inch with a 17/64 throat and a slightly broader sound than the 51. The 53 is wider at 1.033 inch with a tighter 15/64 throat.
