It is a prototype horn Yamaha built. According to Jim Self there are about 5 or 10 of them around. It has 4 double valves (5 thru 3). The 4th valve puts it in CC and re-routes the pipe through the second set of ports on the other 4 valves. So it is basically like any other compensator but with rotary valves. String linkage on the valves. This one plays very nicely. I don't have a picture of it in my files.
