What Year Was My Charles Walter Piano Made? (Serial Number Lookup & Guide)
DIRECT ANSWER
Charles R. Walter pianos can usually be dated reliably by their serial number. On upright and console models, first look for the factory label along the upper inside side panel after opening the top lid; some instruments also have the number on the cast-iron plate near the tuning pins.
Walter pianos were made in relatively small production runs, so their serial numbers progress slowly. Do not confuse the piano’s model number—such as 1520—with its serial number, and use Charles R. Walter in the manufacturer list.

WHERE IS THE SERIAL NUMBER ON A CHARLES WALTER?
Because Charles Walter pianos are famous for their heavy, fine-furniture cabinetry and signature studio vertical designs, finding the number requires knowing exactly where the factory placed these markings.
Charles Walter Upright & Console Pianos
The Inner Rim Paper Label: Open the top lid. Look directly at the upper edge of the inner wooden side panels. You are looking for a dedicated paper sticker containing the factory model designation and the serial number.
The Plate Stencil: On select models, the number may also be printed cleanly on the gold-finished cast iron plate near the tuning pins or bass strings.
Charles Walter Grand Pianos
- The Soundboard Block: Pull the music desk forward or remove it completely. Look down at the gold cast iron plate near the front tuning pins. The serial number is typically stenciled clearly inside a designated cutout area revealing the wood or directly on the iron framework.
