This is a rare vintage Italian made piano accordion. Most (if not all?) Italian manufacturers no longer make such small accordions and despite its obvious age, the build quality of this accordion means it plays nearly as well as when it was first built. It has a 4 voice bass which gives much more depth and power to the left hand than most accordions of this size. All of the reeds are nailed to the resonators (reed blocks) meaning more of the effort of your arm is converted into sound volume and also goes a long way to explaining the durability of this instrument (this is usually only done with Russian and the most expensive Italian instruments today). A superb entry level accordion that should hold its value.
With the accordion in its case, these dimensions increase to 41.5cm (height), 21cm (length) and a depth of 6.35cm. The total weight of this accordion when in its case is 6.35kg.
