Herrburger Brooks action

[Roger H]

My upright piano has been painted on the outside. Inside shows that it was made by Herrburger Brooks.
Is there any other identification I can look for?

[Bill Kibby]

Herrburger Brooks didn't make pianos, they made the action - the working parts of the notes. It only tells us it was made after 1919. If you want to search for clues inside the piano, have a look at

If you can post photos here to show what the whole piano looks like, or email them to me to post, we may be able to tell you more. Meanwhile, there is useful general information about upright pianos at
