The bellows are in okay shape, and so are the keys. But the wax holding the reed blocks in place has completely dried out! Most of the blocks therefore have fallen into the body of the accordion. Setting them back into place would be quite a chore. I may save the reeds to keep as extra parts for other accordions, although I don't know how to check them for pitch without installing them into an accordion first!
The other accordion ("Piccoletta") is a child's beginner accordion I picked up at an estate sale. It had one faulty keyboard reed, and one faulty bass valve. I fixed the bad reed block by resetting it, but I can't figure out why the valve is blocked. I need to rip it open again.
