Good case. Gotta love the King orangish lacquer.
Interesting alternative to compensator - it's at least as large and heavily built as standard Besson ect.
Another bonus is the leadpipe is high enough to actually sit the horn on your lap and not have to cradle it.
You can put it into fake-compensator mode by using a massive 4th valve pull to flat F, E, flat E or even E flat. 3rd valve trigger works, so you can use that to fix the normal 4th valve notes. Well documented on this link - they call it "manually compensating".
