How to determine the age of any petosa

When shopping for a pre-owned petosa accordion, you will want to take into consideration its age.  By determining the age, you will have a better understanding of its history.  At petosa accordions, there are thousands of file cards that hold the records of every accordion built by petosa since 1949.  As accordions are finished, they are serial-numbered and entered into the petosa archives, which list the details of each accordion built since record keeping began. The first two digits of the serial number identify the year of manufacture.  Anyone with a serial number from any petosa accordion can contact us for the information on a specific instrument, including the model, reed configuration, original finish, sale date, and to whom and where it was originally sold.  The historical records of each accordion is another proprietary aspect that makes a petosa unique.  All original petosa accordions are produced from the finest quality materials and workmanship by artisan craftsman. We are proud of the fact that every petosa, although individually different, shares the same unique quality and features that make each and every one of our instruments deserving of the name.
