This is a Geyer-type full double horn. It's recommended for those with less lung capacity who want an easy-to-play instrument. The 4th rotary valve is on the left pinky side, and the valves are aligned in a straight line. The simple winding makes it easy to play, and it's easy for even small women to play, with a bright and clear tone. Rotary action is good. No sticking inside the tubes.
