Hello, i know that Holton was american manufactor or seller during begin 20's century,
and i know Holton are very special ergonomics in generally, because it has extra keys. I see this extra keys on straight soprano, alto, c melody, tenor, but not on curved soprano, and my asking, does it exist ???
