Mundstück Flügelhorn Gregory 5 / Barnd Turboblow

Gregory 5 similar to Parker Spezial
Gregor Bruhin is a Swiss dealer and great jazz flugelhorn player. His Parker mouthpice was taken as a basis for this version.
Since Parker mouthpieces are no longer available, it is worth getting a new Brand Mouthpice. Thanks Gregory
