CAJUN ACCORDION DISCUSSION GROUP
Hi Paul, It looks like an italian box, maybe an excelsior "baton rouge", though I can see why you think it might be a gabbi, looks decent and worth a punt at the price.
Looks like a Povrini I hope I got the spelling right )"kit" accordeon from the 90s. Not Cajun, not particularly good. They were sold under various names and in kit form. Pass Might be POLVERINI.. memory is shot.
