Theoretical Serenellini Button Accordion - 34 treble / 12 bass buttons
(ADG = La/Re/Sol)

This is the accordion I would like to own.  I used PhotoShop computer software to modify a picture of the Model 98 and add a third row of buttons to the treble and 4 additional buttons on the bass.  As far as I know, this accordion is only theoretical.  The "perfect" button layout is the one used by Gabbanelli (Houston, TX) on its TexMex-style instruments.  And the perfect body and finish would be the modified Ciliegio, including 5 treble shifts and 2 bass pull-stops (cut-out for thirds and cut-out for low bass).
Flat Fingerboard (preferred)
