Accordion - Italian-made vintage accordion with case, 120 bass, 41 key

This accordion features 120 bass buttons and 41 piano keys. I am reselling it because it is my second accordion, and I prefer my smaller instrument. I do not know the maker of this instrument or when it was made. I know that it is Italian-made, and by my best estimations, it is more than fifty years old. All bass buttons and keys are functioning with excellent action and tone quality. The bellows do not creak, and the shoulder straps are comfortable. All around, it is a better instrument, in terms of playability, durability, and tone than my $300 accordion which I bought new three years ago. Again, I am keeping the other instrument for its smaller size. The two white buttons above the keys affect the octaves of the treble line (see second photo). When the left button is pressed, the keys play normally. When the right button is pressed, it releases the left button and adds an additional lower octave to the existing treble line. The case is felt-lined and functions properly. This is a high quality instrument in need of a loving owner.
