"bastardized" i like that word.... Ty for answering my question i never asked about the ebolin. I know they still make them and they're like 30 dollars...didn't know if they were any good even though parker used them. I thought it's funny though, wwbw started a thing where you buy a pack of a horn, mpc, etc to suit yourself for jazz, and one i saw for bebop like parker sound was "Ref 54 hummingbird, brilhart ebolin, etc." ...weird And jim, correct me if im wrong but dont you play tenor? if not, for alto are they very loud mouthpieces? I'm using a beechler diamond inlay which completely blows away meyer, selmer, runyon, etc. in loudness. I have looked at junkdude.com and the one mouthpiece they had had a crack in the shank....which sounds like bad news to me...eww. Thanks for the help, any more is greatly appreciated :)

I was wondering if anybody knew what C.S.B means, it is engraved in black lettering on the opposite side of the serial number on my alto tonalin.
