Thank you for viewing. This is a used Vincent Bach "7C" size mouthpiece. It is relatively clean, but there are signs of use such as minor scratches. Please check the photos. (The following is from ChatGPT) Vincent Bach is an American brand that is highly regarded worldwide in the field of brass instruments such as trumpets, trombones, and mouthpieces. The "7C" is the world's most popular standard model for beginners. The "VINCENT BACH CORP." marking may indicate the Mt. Vernon era (1953-1965), or it may be an old (vintage) Bach from the early 70s Elkhart era. Old Bach mouthpieces often have better rim shapes and sound than current models, and are surprisingly valuable. #mouthpiece #Vincent Bach #Vincent Bach #C7
