Hello Concertina.net concertina gurus.
I am the proud owner of a Crane duet, Wheatstone, with a Salvation Army tag. The box itself is rosewood I believe with brown leather bellows, somebody at SA decided it should be their favorite color: um "black"... and has done a rather poor job of refinishing the instrument.
Ah but here's the quirk - it only has 35 buttons, but the right side highest accidental key on the top left row, normally Eb, is instead a clearly in tune "A" note. This gives the player a final high A note to complete the A minor scale.
I wonder if this was by design/request, or just an accident of construction/restoration?
