Graf Hermann serial number
We don't have dated Graf Hermann serial numbers yet. Our serial number lookup covers 214 other makers, and our guide shows where to find the number on your piano.
- Upright piano: open the top lid and look at the cast-iron plate near the tuning pins, usually on the left or right side.
- Grand piano: look on the plate near the tuning pins, under the music desk, or on the soundboard beside the plate.
- Ignore model numbers and patent dates: the serial number is usually 4 to 7 digits long.
