The sound is so cool that, if it were mine, I would would try to find a way to make a viable instrument.
If you had all the time in the world you could special order new bellows of the right size, then make (or ask a builder to make) bellows frames that fit. Store the old bellows for preservation sake.
Actually the thought crossed my mind, but it would be a costly venture in the end. Plus the thing is in tune with itself. I like it how it is, personally.
Sounds great! It is an "A" accordion. I have one of the newer Hohner ones, a "C" with the smaller bellows and 4 stops. Ok to learn on, but noit the same as the La.-built ones for sure. Can you get longer bellows for these accordions?
