Martin Committee III #190401.
Also known as "The Martin Alto" because of the engraving on the bell, these horns are amazing.  Nice dark,
complex sound, very light, refined action.  They a being used more and more as players discover their charms.  This
one is in pristine condition, with about 90% of the original lacquer intact.  Pads a bit on the old side, but plays great
as is.
