This is a great original lacquer vintage Selmer Paris Mark VI alto sax neck. This neck shows minor scratching and lacquer wear, but it has never been pulled down and shows no major past damage or repair. The neck has one tiny ding where the octave key has pushed in to the tube a hair. The original octave key mechanism is in perfect working order. We will replace the neck cork and octave key pad before the neck ships. This is a great option if you have a Mark VI and are missing the original neck, but it will fit many other horns as well. The tenon diameter measures .965”.
