Beautiful example of a hard to find mouthpiece. This is very similar to what Charlie Parker played. Tip opening 0.084″, mild rollover baffle, straight sidewalls slightly pinch an otherwise large chamber. Good player, and unusually large tip opening for a Brilhart. (The facing stamp means little on Brilharts). I think the faint line on the shank end is probably a mold seam, not a crack, as I have owned like 50 Brilharts that all had the same faint line there, but were not cracked at all.
