Alexander 107 w/stopping valve OP

This Alexander 107 descant horn was professionally owned and played in one of America's top orchestras.  It's made of unlacquered yellow brass and has a fabulous compression reading of 1.4 (over SIX ((6)) valves!).  It's one of the rare ones which still sports a fixed bell.  The stopping valves means that you don't have to fret over the intonation issues typically faced when stopping on the Bb side of the horn.  Alexander horns are used world wide by the top orchestras.  This horn is in great condition (though it is tarnished due to not being lacquered). 
Yamaha fixed bell case included.
