This Vincent Bach Corporation–era 7C-T trombone mouthpiece was produced during the Elkhart period (circa 1963–late 1970s). What makes this example notable is its large-shank configuration, designed for .547 large-bore tenor trombones — an uncommon format for a 7C rim and cup.
The familiar 7C profile is typically associated with small-shank applications. Large-shank 7C-T mouthpieces were made in very limited numbers and are no longer produced, making them difficult to find today. This example offers the compact, comfortable feel of a 7C with compatibility for large-bore receivers.
An unusual and practical option for players who prefer a smaller rim and cup on a .547 tenor, or for collectors seeking a lesser-seen Bach Corporation variant.
This Bach Corporation 7C-T large-shank mouthpiece has been sold and is preserved here as part of The Brass Exchange Archive of Sold collection, serving as a reference for players researching uncommon Bach variants.
