I have a handmsde commercial silver flute with closed hole keys and drawn toneholes. Anyone know about these type of Haynes?

I never thought of a Haynes flute as a "student" flute.

Just because it doesn't have open holes or a B foot does not make it a student flute.

I believe you're referring to a "commercial model" Haynes. I've tried a few at conventions, and they're a lot of fun to play. Not a student flute by any stretch of the imagination.

Whoops, didn't realize that you knew it was commercial model already. I stand by the rest of my post, though.
