This is an antique Soprani Petite accordion from the 1930s. Fun Fact: it was originally marketed for women because of its smaller size and weight. It is 100% fully functional. Every single key, bass button, air switch, and register works. There are 1 or 2 bass buttons that are a little bit looser than the others from being used more frequently, but other than that I can appreciate no functional deficits. The only cosmetic defect present in the bellows is a bit of fraying/erosion in the right corner bellow that does not affect the sound of the instrument. There are no major cosmetic defects in the holes of the lining or in the air valves. The leather straps are original and do show some wear and tear, but have not lost their structural integrity. I have personally played this accordion with the straps on for multiple hours and found no issues with adjusting them or feeling that they were loose. The case is included and the lining inside is still intact. The locks on the outside function well and there are no loose bolts. The handle is not loose. There is some expected wear on the outside of the case and on the trim.
Please message me if you would like more information. I am happy to take a video of me playing it or showing it off in further detail for buyers who are seriously interested.
