Old Vincent Bach Corp. 7C Trumpet Mouthpiece 100 grams 23mm Large Cup 60s mod. It became a practice evenThis 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
