The Johnston Selmer mouthpieces exhibit the standard 40's style short, stubby, large chamber design that you see with many American saxophones. It's a pretty dark sound and a small tip. This would be good for refacing practice - you could open it to .072 and pickup a bit of rollover baffle at the same time, and you could sound good in concert band on a vintage alto with a mouthpiece that was designed to tune well on it.
