[pianotech] 1965 Yamaha G-1

[David Ilvedson]

That's a beauty, Barbara.   If you are going to file the hammers and repin, you will make it sound a heck of a lot better than it does.   Of course that will include aligning with the strings some regulation and voicing.   It might be worth the comparison for the owners of new parts (might be able to get Hammer, Shanks and Flanges read to go) and what you can do with no warranty.
