Bore at top of left keyed joint: 15.0 or 15.1
At bottom of same joint: 14.9
This seems to be just the same as the Bundy. I don't see any difference in the key work, bore, or in intonation.
This instrument is still very adequate for a beginner.
My friend Paul at the music store agrees with me: It looks like Selmer stopped producing the old standby Bundy, and simply has started producing the same horn under the Selmer name.
