Conn Cavalier HR

I restored this as a favor to Ron. Many Cavaliers were made in metal. This one was made of hard rubber for the two keyed joints. The bell and barrel seem to be made of something more like Resonite/Plastic.

Bore at top: 15.4mm (huge!), in middle 15.1. The bore makes this a jazz horn, like the Conn wooden instruments. Should be easy playing with a big tone.

Barrel 64mm Not just any barrel will fit on this horn. The outer size of the tuning tenon is larger than any of my barrels.

Pads: 4 x 15.5mm, 2 x 11mm, 9.5mm and one 8.5.

For instruments with a large bore, I recommend pulling some in the center to avoid flatness in the chalemeau regeister, but not so much as to make the middle clarion register flat.

The problem with this model is that the keys are of cast pot metal, famous for being brittle, all with numbers on the back side. These can break easily if the horn is dropped, but are sturdy and stay in adjustment otherwise. Don't try to adjust key travel by bending these keys! It is better to use other methods of adjusting, like using cork and pad thickness.

The E-flat/B-flat key below is not going to bend!

This horn has the little set screws that hold the short pivot screws, seen near the C#/G# key. And the set screws also are a German trait.

The throat tone G# key is unusual in shape.

[Nov2012] This is a German shape!

30Jun09 Conn plastic, but not marked Cavalier. E64671 I would say this is older, perhaps 1940 vintage, somewhat better than keywork than the Cavalier. It still has the set screws, but not the funny shaped keys. Keys are not stamped with numbers.

Bore at top: 15.2. 15.0 at the middle transition.

Takes one size smaller pads than normal clarinets. 9mm on top, instead of 9.5.
