◼️Warburton ◼️Trumpet Mouthpiece ◼️6MD top series 80 7 backbore ◼️GP (Gold Plated) ◼️Outer box: None ◼️There are some areas where the plating is thin, but overall the gold plating is still beautiful. The shank looks like it has intentional lines, but the gold plating is applied nicely. The throat expands beautifully from the top to the backbore.
