The entered serial number W2766222 was not made for the US market, OR this may not be Acoustic Pianos Serial Number. What gives?īrandon, plugged your serial number into the Yamaha website serial number look up and got this: It looked like a U3, but had no model designation cast into the plate or indicated otherwise. What does the 'W' stand for? And the little emblem cast into the plate that usually says 'Yamaha Hamamatsu' only had 'Yamaha' on it - like a Yamaha that was not made in Japan. Looked it up in Pierce and that serial number was assigned in 1978 (for a Japanese Yamaha). I tuned a Yamaha upright yesterday - looked a bit older - 1970s maybe? The serial number is W 2766222. It appears that if they were made in Japan, the regular serial numbers were applied.īut here is another question. However, we do see many grey market Yamahas in Florida and it's always appeared to me that there is no difference between serial numbers on regular and grey market pianos.
