According to my copy of the Pierce Piano Atlas, the Baldwin piano with serial number 127398 was manufactured in 1954.
I have a Baldwin 621 piano with a different serial number and it was bought in 1988.
I have one that the serial number is close and it was built in 1833. Not at home so I don't have exact serial #, but this seems close. Do you have any idea how much it is worth or any on in the...
According to this.... http://www.bluebookofpianos.com/serial1.htm#WILLIS%20&%20SONS your piano was built (roughly) in 1910.
It should be around 1974. (For References see Related Links below)
