It was a kind of a hard decision to make whether the keytops are to be removed or remain since this celluloid material is no longer in production. However, the celluloid is weaker compared to today’s plastic. But the gradation color and its old fashioned look is nice, so we decide to keep this. In the picture, the left side is polished and the right side is as it was.
The balance hole adjustment was totally different from today’s pianos. A plate of beech wood is attached at the bottom of a key but this doesn’t appear on today’s pianos. It took a while to find out why the hole was so hard.
