This Atkinson double horn has a Kruspe wrap and is made in an unlacquered yellow brass. It has recently been chemically cleaned at a shop in New York and all valves and slides are moving with ease. The valve compression is at about 7.0, meaning it would be smart to consider a valve rebuild on the instrument. There is a pinky hook soldered on as well as a lever spit valve on the main tuning slide. Comes with an old MB5 detachable bell horn case that has been heavily used.
