Ben Davis Streamline Vocaltone

[mpjbiker]

Hi all, was having a rummage the other day, and I found a bari mouthpiece as above. I haven't tried it, as it is seven sided plus the table, so I haven't got a ligature to fit it. Anyone know anything about them? Is it worth anything (ever hopeful!)? Seems to be plastic with silver engraved end (the end that fits onto the crook),
Cheers, Martin.

Might it be Ben Davis rather than Ron? If so there's been a bit of discussion previously.
