I do not believe pianos were done without balance rail punchings. I have seen them totally eaten away and/or removed by a previous (technician?). My advice is to determine the correct key height, then add at least the thin punching, preferably with a .010 punching under each one in order to be able to adjust the key level downward, if necessary, when you do your final leveling. A piano without balance rail punchings would be somewhat noisy, to say the least.

I noticed that there are no felt punching on the balance rail: is this common for circa 1925 pianos (sn 114743 if any of you kind folks have an atlas handy)? I'm guessing I shouldn't "add" felts where I don't find them. John Delmore
