Yesterday, there was a customer who took some photographs of the interior part of his piano. The customer would like me to ascertain the age of the piano.
I would like to share with all of you that generally, as for YAMAHA piano, the serial number has reached 62xxxxx to a seven digits numbering. The serial number of this second hand piano is 15xxxxx, which is about 40 years. In order to be more accurate, there is an index book that records the years of manufacturing of all the pianos of all the brands in Japan. Besides, the structure of this piano is considerably “old fashion”, and it seems that the hamper of the piano has been treated accordingly. Hence, it is more accurate to look at the actual instrument.
