Rare YAMAHA MINOR CHORD NO.OS 210 Orchestra Series 8 chords (Fm Cm Am Em Bm Dm Gm B♭m) This is a rare Yamaha Orchestra Series harmonica for ensemble playing, featuring minor chords. There are some minor scratches and scuffs, but it is generally in good condition. I couldn't find much detailed information even after searching. I think this is a very unusual harmonica. #Yamaha #YAMAHA #Harmonica #Ensemble #Harp #Orchestra Series #Orchestra Series #Rare #Vintage #Vintage #Retro #Showa
