The serial number dates this piano back to 1957 based on Hamilton serial numbers. The Hamilton company was controlled by Baldwin, but was not Baldwin. So the name on front is misleading. Certainly the updates and work done to the piano help with value, but I would be surprised if a piano from the 50's needed a new pin board and pins. It appears to be in pretty good shape now based on the photos. I would strongly recommend an independent 3rd party come out and inspect the piano for you if you're considering buying to ensure quality of work done. As described, I would recommend a value range of approximately $5,500-$7,000.

Ok, what information do you want? It doesn't matter that the piano is "unmarked" as we know what the instrument is. Please tell me how I can best help.
