Alexander Bb w/F extension and stopping valve

I have never seen an Alex Bb with a built in F extension.  This horn is fabulous.  The valves have perfect compression (0.1) - they have been rebuilt.  It has a Lawson leadpipe, AND it has a stopping valve along with an F extension.
Easy playing - light, and facile.  Perfect for so many applications - solo, opera, quintet etc etc.  Professionally owned and maintained.
This horn is made of unlacquered yellow brass.  There are 2 guards installed at the top of the horn (where you carry it).  There are no thin spots, and the gusseting is gorgeous displaying the fine craftsmanship of the hand hammered flare.
Older fixed bell case included if desired.
