Re: What kind of soprano did Bechet play?
I agree with you. It definitely looks like a buescher in any pics I have seen.
Black rollers not white. Engraving is very Buescher looking. Round pearl G#. seen in the earlier Bueschers.
I am not sure when the snap in resonators started with Buescher, but his does not have them. Pictures with white pads had simple rivet pads on the lower keys.
But I do not know for sure.
It may be a european maker since he spent a lot of time there.
Not like it matters.
