I do not know much about this item I recently received it. The Bellows blow air through the Reeds and produce sound when keys are pressed. I am sure it will need a complete overhaul. I never played the accordion. All I know is that notes come out not missing any inlay or mother of pearl. All intact?

From what I’ve seen it may be Italian or Polish. The keys need a good dusting but I will leave cleaning up to the next owner.
