Piano, Organ, and Keyboard/Hallet and Davis Square Grand


I bought this piano about 30 years ago.  My parents have a large colonial farmhouse and I shipped the piano to them as a gift as for the music room.   My folks are now in their 80's and need to convert the music room into a downstairs bedroom.  The piano is in very good condition-  I saw one reconditioned and advertised online-the exact same model for 28K.   I don't know what to do with it-I have no idea of value or how to advertise… What is your opinion of square grands?  Are they a dinosaur that should become extinct?

Hi Scott:

My experience with these pianos is that they are never cost effective to rebuild.

I have done rebuildings on these for those who 'had' to keep them in the family, or wanted them for their furniture value.

However, in all cases, parts for these have to be custom made and there aren't many alive who do this.

They are a dinosaur and as such are a conversation piece. They are not worth much as instruments.

"Rebuilders" will tell you, "if you give me 10K you can sell it for 28K". The advice I have for the owner is to offer it to the "rebuilder" for 5K and see how that goes!

I would advertise it on ebay or craigslist and see who responds.

Who seems to want these are antique dealers and home designers on the higher end.

I hope that helped.
