Piano, Organ, and Keyboard/Cable & Sons Baby Grand


Directing this question to you since the latest question was also about this same type of piano.

My question is where is the serial# or ID plate on a Cable & Son Baby Grand Piano usually placed? The only printing of sorts is on the under side of the keyboard cover.  Lift that up for play and it states the name.  I have been all around the top, under the lid, on the floor under the piano and can't find anything.  Any tip would be great to hear. Thanks.

Hi Laura:

...and sometimes...there just plain isn't one.

That's unusual of course!

Do you know the history of the piano?

I ask because sometimes during a re-stringing of the piano, the original serial number is painted over.

Also...sometimes the serial number is hidden or embedded in the furniture.

The front of  the piano, where you play has a strip of wood called the key slip. This is the piece of furniture behind which the front of the key slips.

In some cases it pulls up and away hold in by steel pins. In other cases, 3 or 4 screws going from underneath hold it in.

If you feel adventurous...take it off and look on the inside of it, and on the key frame that it hides. The serial number could be there!

Let me know!
