Piano, Organ, and Keyboard/victorian rosewood square grand piano/organ


My son just acquired the above mentioned piano manufactured by gilbert & Co. with a J.S. Ivers organ attachment, serial number 3490.We're trying to find out historical information, date of manufacture and possible value after refurbishing.
He has re-built a Steinway model O from 1922 and is getting ready for another challenge.

Hi Andrew:

These old "coffins" were popular at one time.

The worth is in the eye of the owner.

As a long time rebuilder, I would always caution rebuilding square pianos on speculation of worth!!!!

First off...action parts must be custom made. I did this for a lot of rebuilders. The only person that benefited from that was I.

So your son can do this out of a labor of love...but worth won't come from it.

The piano was manufacture c. 1860.

It will need complete restoration: sound board, block, bridges, action!!!

For every dollar invested in either parts or labor you will net a penny.
