Your Piano's Age

How to find out the age of your piano.

Do you know the age of your piano?

If you are curious or perhaps you wish to accurately understand the background of your piano, we can help!

Simply follow these easy steps:

  1. Send an e-mail to Dr. Ken Mahood with the following information:
    1. Your name and return e-mail address.
    2. The name and serial number of your piano.
  2. Send $12.00 via PayPal to

As soon as payment is confirmed, you will receive a comprehensive report on your instrument. IMPORTANT: In some cases, the piano manufacturer kept incomplete records. We use multiple sources to provide as much information as possible. However, we never know if we will find a few words or several pages. Records were not kept for some pianos manufactured before 1850.

KM International and Dr. Ken Mahood are not responsible for the content about the instrument you are inquiring about. We can only pledge we will do our best to give you as much information as exists in the public records.

Locating your old piano serial number:

Consoles, Spinets and Studio uprights

a. Lift up the cover behind the music rack. The serial # can be either on the "pinblock" (the wood 'thing' that runs along the entire top of the piano).
OR, it might be either stenciled in black or in 'relief' on the "HARP" itself (the steel frame that holds all the strings and is a brass or possibly gold color).
b. It could be on the actual rear of the piano between the wood posts which hold up the instrument
c. If you still cannot find the serial number, please email me, Dr. Ken
Mahood at :

Grands, babygrands, parlor grands, concert grands, etc.

a. The serial number is always stenciled or in high-relief on the physical harp of the instrument, that is, the steel frame on which all the strings are attached. You may have to removed the music rack by sliding it out of the front of the piano.
b. If you still cannot find the serial number, please email me, Dr. Ken
