SOLD - Straight side walls (Brilhart) into a larger throat/chamber than narrows back to bore size. Identical to others yet without the metal shank band, thus cheaper.
SOLD - A nice, used STM now refaced to help improve seals and curve. It was originally a 6* and not it is about 0.099" or about 6** or better said: "7-". I leveled the table, helped set the curve, leveled the tip seal, reset the baffle and will do some replating to seal the brass.
SOLD - It's a nice jazz tone with a centered focus yet round warmth. Sounds like a mix of a Meyer crossed with Otto Link rubbers.
SOLD - A modern era Couf mouthpiece set. Still made of great, hard rubber it has a side walls into a medium chamber.
SOLD - The very vintage "H. Selmer Paris" mouthpiece with a large chamber and original tip of 0.037". It can be refaced to your desired tip. These were made from 1885-1925 with changing logos, thus I think this is in the 1910s-25 era. These have a very large chamber with rounded side walls.
SOLD - Post-1972, this one looks vintage, but that look can't be verified by the color alone. The rails look nice and thin and may allow for a great resonance. Also comes with original white box.
SOLD - It tends towards a traditional Jazz sound, but is quite versatile; it has a slight roll-over baffle, precision-sculpted inner sidewalls, and TW's True Large Chamber for a simply huge and alive vintage sound.
SOLD - Large chamber mouthpiece from the 1920s/30s. These are in high demand for vintage baritones to help even out the intonation issues.
