A 6 1/2AL trombone mouthpiece made by Vincent Bach Corp. It's a large shank. This is from the era right after Mt. Vernon. It's called "Near Dot" because the dots are close together. It's a large shank. The combination of a Bach 42B and a 6 1/2 was once a classic. Even the young M. Becker used this combination with a Bach 42B yellow bell and nickel slide, along with an AM mouthpiece. It's the sound of Martin Pärssinen at the Munich Competition! - Brand: Vincent Bach Corp. - Model: 6 1/2AL - Type: Trombone Mouthpiece The plating and shank show some wear, but it's in good condition. It has a noticeably softer sound than current models. I polished the first two a little. Thank you for looking.
