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.
"A" 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.
"B" Models have medium deep cups, #7 backbores, and have a full, Teutonic tone with great volume.
"C" Models have medium cups, #10 backbores, and are preferred by many players that alternate between Bb, C and D trumpet.
"D" 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.
"E" Models have shallow cups, #117 backbores, and are designed for use on soprano and piccolo trumpets. Also preferred by extreme high register players.
"F" Models have extra-shallow cups, #76 backbores, and are also preferred by extreme high register players.
"V" 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.
"W" Models have a wide, cushion rim for soft, thick lips.
