Pan American single French horn,(owned by Conn) with additional (longer) slide to convert it to the key of Bb (from F). (Double horns simply use a 4th valve to change the key). Original mouthpiece and hard padded case included. This horn was made many years ago, has a few small dings and slight tarnish, but looks good and plays flawlessly. See photos. DONT RENT (monthly cost averages at least $50/mo). Calls are best
