Alexander Model 90 Bb w/stopping valve LI

This is a FUN horn to play.  It is so light and versatile - and due to the fact that it has perfect compression (0.1) it is incredibly secure in all the ranges.  The stopping valve allows for in-tune gestopf on the Bb side of the horn.  It's made of unlacquered gold brass with an Alexander nickel ring set.  A Duerk single ball flipper has been added.  It has mechanical linkages, so no worries about ever breaking a string  mid-performance.
