It is remarkable that data on piano serial numbers has survived so well for over a century. However, some inaccuracies are inevitable. These serial numbers are to be used only as a rough guide to a piano's age. An exact date does not make a material difference to a piano assessment. To be within 2 to 5 years is accurate enough to give an informed report on a piano.
