This is a full double horn in F/B♭ by Playtech. The bell is detachable, making the case quite compact. There are some dents on the bell, but they do not affect the attachment to the body or playing. The rotary valves are stuck, but it was used about a year ago, so I think a repairman can fix it easily. I bought this as a stopgap measure because the school club was short on full double horns until a new one could be purchased. I am not a specialist (I can't play at all), but according to someone who played it, it's a model that can be played easily. It may not be enough for experienced players, but it is recommended for those who want to try playing the horn for the first time or want to use it as a stepping stone before buying a higher-grade model. The body, detachable bell, case, and mouthpiece are included.
