I recently purchased this piano from an estate. I knew the owner and played this piano on numerous occasions prior to her death. The Piano has a brass number (98) on the lid. I know that it has had a career in Philadelphia at the Curtis Institute and Philadelphia Orchestra among others and I have a listing of performers who supposedly used this piano in concert. However, are there any ideas about how one can find out more information about this piano? I contacted Steinway and they basically told me that they have records about its construction but don't have time to even help me with that information.
