This is a VERY rare extended/shifted keyboard, the same accordion the legendary Art Van Damme played at one point in his career.
The keyboard layout is G to high C.
This is a DOUBLE TONE CHAMBER with TWO low reeds and a middle. This is how Van Damme wanted it as he never used the piccolo reed. There is one LOW and one MIDDLE in the chamber.
There are 10 treble switches plus the palm master.
There is a sliding mute switch for added mellowness.
There are 6 bass switches.
This is 3/5 reed arrangement.
The microphones were old and non functioning and have been removed. They can easily be replaced with internal or the more efficient external mics (I highly recommend either external mics or playing through a microphone if amplification is needed). I always played it acoustically without needing microphones.
There is a small scratch on the palm master as I have photographed, and light tarnish on the bass switches. None of this effects playability at all!
The accordion is in tune to my ears, but ALL accordions no matter how old, can use touchups.
I am selling because I have suffered irreversible health issues (6 strokes in the last 2 years) and just do not want to damage this accordion in any way by playing it.
Liberty Bellows was selling one like this for $3900 and I will give you the link to hear their accordion:

You will enjoy this accordion. I planned on keeping it for life. But "life" got in the way.
Please consider buying this as it will help me with the med bills and it will give you joy to play it.
