Vincent Bach Mouthpiece 4G - Mouthpiece Brand: Vincent Bach - Mouthpiece Size: 4G Thank you for viewing. I purchased this about 20 years ago, but I haven't used it much and it's been stored away. I think it's in good condition, but there is a 2mm hairline scratch on the rim. Please refrain from purchasing if you are concerned. No box. The last photo is a comparison with a new model. Please check the difference in the engraving.
