Piano, Organ, and Keyboard/christman sons piano


Hello. We have a christman sons piano and cannot locate the serial number. We have had the piano for 19 years and just found that it has been refinished professionally. It appears it was once black and was refinished in a maple finish.  I know the history back to 1978.  I had a technician look at the piano and he told us the issues (which were few). Is there any way to date the instrument. There are no decals or serial number the technician or I can locate.  Thank you for your time.  Rick Barrett

Hi Rick:

Can I assume this is a vertical piano?

Christman started building in 1885 with serial number 1000 to 1929 with serial number 41000.

I doubt what the refinisher did removed the serial number.

Here are some "hiding places" you can look:

1. under the key bed (directly on the wood and the piano under the keys.

2. On the back. This would probably be a stamped number right into the wood.

3. Inside: on the very top under the lid. Or, on the steel plate in and around the tuning pins.

4. Inside bottom: take the kneeboard off. There is usually a spring type clip holding it in place. This, by the way, is the board under the keyboard over the pedals that covers the bottom portion of the piano. Look for the serial number on the sides of the steel struts.

You will need a flashlight to help you.

What are the "issues" with the piano.

Let me know how you do.
