This is an OS Phoenix model harp with a Willy Bryant "slider" attachment (plays all keys call shop for more information). It's a 21 bar, black harp with gold lettering, black OS gig bag and wrench. There are extra labels pertaining to 3 positions of each chord. Tuning for slider harp only goes to low "C" but it plays in all keys by shifting the chord bars up or down by a notch.  The #1string had to be left off to leave room.
