Hello all. This is my first time here. My grandfather recently passed away and I was left his accordion. I have never played before and have a few questions. First, It sounds like there are loose pieces inside of it, any thoughts on what this may be? Also I know nothing about the brand/model and cant find out if it is something a beginner should be playing. It has the following markings on it. Bianchi, G. Sperati & F., Castelfidardo. Does this mean anything to anyone? Thank you for your help.
