I don't think modern Bueschers have nothing to do with the great American Vintage horns. Those horns were manufactured in Elkhart Indiana. Selmer, who owns the Buescher name, recycled the brand and currently sell Taiwanese horns under it. That's not to say that they're poor instruments, A lot of Taiwanese horns are quite good these days, but I can't see them having any physical relation to the old 400s and Aristocrats.
