This is a beautiful Italian accordion. It is a 3/5 reed with a LMM treble reed configuration and a 16 1/2" keyboard. I've done very extensive work on this instrument. I've replaced all the reed wax and most of the reed leathers. I have rebuilt the treble and bass side action with new pads in the treble side. When it came time to tune it I made the decision to tune the whole accordion down to A-440. I tuned the sharp middle to a nice moderately wet musette. I also installed a new back pad behind the keyboard. It's now a lovely strolling accordion for those with smaller hands. It has a fast keyboard, it is well balanced, and being at A-440, the band won't have to tune to you.
