Old Vincent Bach Corp. 7C Trumpet Mouthpiece 100 grams 23mm Large Cup 60s mod. It is unlined and theThis is an older Vincent Bach trumpet 7C mouthpiece that came out of the basement of a 1920s house. Most everything in the basement was old from the 20s to the 60s, so I assume that this is an old example. There is a dot after Corp my understanding is that the dot signifies a wider bore. This mouthpiece also weighs more than a regular modern example, which normally would weigh 68 grams, whereas this one weighs 100 grams. Please check the measurements
