Where do I find the serial number on a Baldwin Acrosonic Spinet piano?

The serial number on a Baldwin Acrosonic Spinet piano is typically located on the metal plate inside the piano, often near the tuning pins. You may need to open the piano lid and look inside the body, usually on the right side. Alternatively, it can sometimes be found on the back of the piano or on the keybed. If you're having trouble locating it, consult the piano's manual or contact a professional piano technician for assistance.
