A Specialty Backbore for Vintage Trumpets
The ACB VNT Vintage trumpet shank backbore is specially designed to work with pre 1930's classic trumpet shanks (King Liberties, Holton Revelation, Martin Handcrafts, etc). Right now only one size is available, a fairly straight tapered semi-open custom backbore.
Like all of our ACB backbores it's compatible with any standard "Warburton" threaded top (like my ACBs, Wedge, Warburton, Jim New, Pickett, Greg Black, etc).
If you have any questions about these backbores (or any of our mouthpiece products), please call our Mouthpiece Hotline: +1-781-816-9664
If you have additional questions send us an email.
