Rim shape is described for each individual model. Model numbers progress numerically from model #1 with the largest cup diameter, to model #20C with the smallest cup diameter.
Cup depths are notated with letters. "A" cups are the deepest; standard cups have no letter designation; progressively shallower cups are marked B through F.
Models have very deep cups, #24 backbores, and emit a large, dark sound.
Models with no letter designation have deep cups, #10 backbores, and produce a rich, full, clear tone.
Models have medium deep cups, #7 backbores, and have a full, Teutonic tone with great volume.
Models have medium cups, #10 backbores, and are preferred by many players that alternate between Bb, C and D trumpet.
Models have medium-shallow cups, #76 backbores, and produce a sparkling, brilliant tone, especially in the high register. Artists who continually play in the extreme high register use them to advantage.
Models have shallow cups, #117 backbores, and are designed for use on soprano and piccolo trumpets. Also preferred by extreme high register players.
Models have extra-shallow cups, #76 backbores, and are also preferred by extreme high register players.
Models have V style cups. "V" designates a very deep cup, #20 throat, and #25 backbore; "MV" designates a medium deep cup, #25 throat, and #25 backbore; "SV" designates a shallow cup, #25 throat, and #25 backbore.
Models have a wide, cushion rim for soft, thick lips.
Model No. - Rim Shape
- 11C - Medium wide
A beautiful brilliant C trumpet tone that requires little effort to play in the high register, yet with a free low range.
- 11D - Medium wide, well rounded
Produces a brilliant tone, effective in the high register. Good for players not having a strong embouchure.
- 11DW - Extra wide
Players with thick, fleshy lips, especially those who cannot rely on the strength of their lip muscles, can use this cushion rim mouthpiece to advantage. Produces crisp, easy top tones.
- 11EW - Extra wide, rather high toward the inner edge
A cushion-rim mouthpiece especially designed for the extreme high register. Because of the extra shallow cup, the tone is very brilliant, piercing, and cuts well. For players who have heavier than normal pressure in the high register.
- 11½A - Medium wide, well rounded
Similar to No. 11A, but slightly smaller. Produces a rich, round tone.
- 11½C - Medium wide
A brilliant, scintillating tone, very easy response and good all-around register.
- 11¾C - Medium wide, well rounded
Easy playing, with a compact, brilliant tone. Recommended for players with sensitive embouchures and narrow lips.
- 11¾CW - Fairly wide, rather flat, not too sharp
A cushion rim for players with soft, fleshy lips who rely on above average pressure. Responds easily in the high register.
- 12 - Broad, rather flat
This popular model produces a full, mellow tone. A good choice for players of the English or Italian school who are accustomed to small mouthpieces and players with heavy, weak lips.

The same rim as No. 12, with a slightly shallower cup to make the tone more lively. High register responds well.
- 12C - Broad, rather flat
Brilliant tone, easy high register for trumpeters who have to play forte in the upper range and for players with heavy, weak lips have difficulty with the high tones.
- 12CW - Broad, rather flat toward the inside
Cup diameter and depth are the same as No. 12C, extra wide cushion rim.
- 17 - Medium wide
A small mouthpiece with a solid, compact tone. Players with thin lips find this model highly satisfactory.
- 17C - Medium wide
A lively, clear and brilliant tone, for players with thin lips whose embouchures tire easily.
