All the horns that are in here are literally all I've ever seen. While these horns bear a strong resemblance to other Germanic horns, most notably the Keilwerths and Kohlerts, there's enough different in them that I can't definitively say "Kohlert" or "Max Keilwerth" or whatever. I've heard of and seen a horn called a "Buescher Atlantic." There were some Germanic horns with the Buescher name, but obviously not made by the Buescher company in the US.
