Dating Your Baldwin Piano
Once America's largest and most famous piano manufacturer, Baldwin was long considered the American alternative to Steinway before undergoing major corporate changes that shifted production overseas.
Where to Find the Serial Number
To accurately date your Baldwin, you first need to locate its serial number. On most pianos, this is stamped on the gold-colored cast iron plate inside the instrument.
- On Uprights: Open the top lid and look inside. The number is usually printed on the plate near the top, often toward the center or right side.
- On Grands: Slide the music desk back or remove it. Look at the cast iron plate between the tuning pins.
