This is a glorious American piano in wonderful condition. The strings, hammers and other action parts appear to have been replaced with high quality parts not that long ago and are performing on a very high level. More than that, they are the right fit for this particular piano as is revealed in the sound and playing experience.
The case is also quite beautiful and appears to have been refinished some time ago. The piano has a vintage expressive player system that is restorable. It has absolutely no effect upon the performance of the piano and sits invisibly beneath the keyboard.
Mason & Hamlin pianos from this era are in great demand because this is a period in their history known for exceptional quality. Since the piano has been kept up with extensive work in its history, it should provide years of high level playing.
